Allow a fixed framebuffer address to be assigned to the framebuffer device

The call to xilinxfb_assign is getting unwieldy when adding features
to the Xilinx framebuffer driver. Change xilinxfb_assign() to accept
a pointer to a xilinxfb_platform_data structure to prepare for adding

This patch adds support for powering on and off the Samsung LTV350QV LCD
panel via SPI. The driver responds to framebuffer power management, it
powers off the panel on reboot/halt/poweroff. It can also be controlled
through sysfs. The panel is powered up when the module is loaded, and off
when the module is unloaded. Verified on AVR32 STK1000.

After fixing the too small memory allocation in cr_backlight_probe()
from drivers/video/backlight/cr_bllcd.c
(commit e3bbb3f05339de438faf54124f25c92e6fe4ac2e) I noticed that the
Coverity checker also thought there were a few memory leaks in there.
I took a closer look and confirmed that there were indeed several
leaks.
At the start of the function we allocate storage for a
'struct cr_panel' and store the pointer in a variable named 'crp'.
Then we call pci_get_device() and pci_read_config_byte() and if
either of them fail we return without freeing the memory allocated
for the 'struct cr_panel'. These two leaks are easy to fix since we
don't even use 'crp' for anything up to this point, so I simply
moved the allocation further down in the function so it only happens
just before we actually need it.
A bit further down we call backlight_device_register() and store the
result in 'crp->cr_backlight_device'. In case of error we return
'crp->cr_backlight_device' from the function, thus leaking 'crp'
itself. The same thing happens with the call to lcd_device_register().
To fix these two leaks I declare two new pointers to hold the return
values, so that in case of error we can return the pointer (as before)
but without leaking 'crp'.
This version of the patch also adds missing
backlight_device_unregister() / lcd_device_unregister() / pci_dev_put()
calls to error paths.
Thanks to Richard Purdie <rpurdie@rpsys.net> for noticing.

Three main sets of changes:
1) dmi_get_system_info() return value should have been marked const,
since callers should not be changing that data.
2) const-ify DMI internals, since DMI firmware tables should,
whenever possible, be marked const to ensure we never ever write to
that data area.
3) const-ify DMI API, to enable marking tables const where possible
in low-level drivers.
And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.
The bulk of the changes are #2 and #3, which are interrelated. #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

This fixes a problem introduced with commit
b5f2f4d1a6d7efde39cfb5e1d034981c69f2214c
The commit added a wrong chip definition to radeonfb which causes
a blank console on my Laptop if radeonfb is loaded.
The patch
- renames PCI_CHIP_RS485_5975 to PCI_CHIP_RS482_5975
- corrects the chip family (RS480 instead of R300) for 0x5975
- ensures that PCI IDs are in ascending order in ati_ids.h

Intel framebuffer mis-calculated pixel clocks.
The pixel clock (and thus both H and V sync) will be slower than requested, so
if you set the minimum allowed the display may not sync. In case of really
old CRT display it could theoretically damage it.
I'm using it with PAL TV (using RGB input - SCART connector) and the bug
prevented it from working at all (TV requirements are more strict and made the
bug visible).

This builds upon my previous attempts to resolve some jitter problems seen
with the Matrox G450 and G550 -based cards, including odd disparities observed
between x86 and Power -based machines in a somewhat less hackish way (removing
the hacked ifdefs).
Apparently, preference should be given to use the DVI PLL when frequencies
permit, the Standard PLL otherwise. The max pixel clock for the panellink
interface is extracted from the PInS information on the card and used as a
limit to determine which PLL to use.

- better handling of the pvr2 registers based on more up to date information.
Testing shows that it seems to work pretty well at 16bpp, 24bpp and 32bpp -
including proper rendering of the boot logo at all levels (previously this was
a bit broken even at 16bpp) and giving white against black text. Really
detailed testing (eg with X11) requires support for the maple bus - which
isn't (currently - next project assuming this is okay) available, but I have
no reason to think this is broken.

This driver will oops when the pseudo_palette[] is written as u32 but not when
written as u16. When written as u32, it corrupts the adjacent 'mmio_base'
field of struct pvr2fb_par. Fix by using framebuffer_alloc()/release() to
allocate struct fb_info and struct pvr2fb_par, and create the pseudo_palette[]
as part of struct pvr2fb_par.

Visualize-EG, Graffiti and A4450A graphics cards on PARISC can
be configured in double-buffer and standard mode, but the stifb
driver supports standard mode only.
This patch detects double-buffered cards more reliable.
It is a real bugfix for a very nasty problem for all parisc users which have
wrongly configured their graphic card. The problem: The stifb graphics driver
will not detect that the card is wrongly configured and then nevertheless just
enables the graphics mode, which it shouldn't. In the end, the user will see
no further updates / boot messages on the screen.
We had documented this problem already on our FAQ
(http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics
with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem.
So having this fix in as early as possible can help us.
