Convert calls to free_irq so that the second argument is the same as the
last argument of the corresponding call to request_irq.  Without this
property, free_irq does nothing.

pvr2fb special cases its init/exit routines which causes spurious section
mismatches. Set the board_driver array __refdata to silence them.

Both the store queue API and the PMB remapping take unsigned long for
their pgprot flags, which cuts off the extended protection bits. In the
case of the PMB this isn't really a problem since the cache attribute
bits that we care about are all in the lower 32-bits, but we do it just
to be safe. The store queue remapping on the other hand depends on the
extended prot bits for enabling userspace access to the mappings.

With arch/sh/drivers/dma/ always being built, the Dreamcast DMA engines
are being unconditionally built in, regardless of whether the DMA API is
enabled or not. This is a regression from previous behaviour, but there
is not much advantage in building them all in unconditionally regardless.
Add a new config option to make it optional, and update the only user of
it to reflect that.

Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports:

  CC      drivers/video/pvr2fb.o
  LD      drivers/video/built-in.o
WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix
The function pvr2fb_check_var() references
the variable __devinitdata pvr2_fix.
This is often because pvr2fb_check_var lacks a __devinitdata
annotation or the annotation of pvr2_fix is wrong.

This is obviously crap as no such reference exists, but it's a bit
closer to reality from older versions which blamed the PCI table. The
real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(),
as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least
that part is right).

pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so
we just reference that explicitly instead.

This patch replaces <asm/uaccess.h> with <linux/uaccess.h> after the
checkpatch.pl hint.  The include of <asm/uaccess.h> is removed if the driver
does not use it.

The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware
synchronisation between the maple bus and the VBLANK to poll the maple
bus. This patch makes the interrupt shareable.

By definition the interrupt is for both devices.

- 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.
