Make Primecell driver probe functions take a const pointer to their
ID tables.  Drivers should never modify their ID tables in their
probe handler.

The ARM CLCD PL110 controller in TFT mode provides two output formats
based on whether the controller is in 24bpp mode or not - either 5551
or 888.  PL111 augments this with a 444 and 565 modes.

Some implementations provide an external MUX on the PL110 output to
reassign the bits to achieve 565 mode.

Provide a system of capability flags to allow the CLCD driver to work
out what is supported by each panel and board, and therefore which
display formats are permitted.

has been found.  Display the revision as an unsigned decimal, and
display only the first 8 hex digits of the base address unless it's
larger.

VIDEO: amba clcd: don't disable an already disabled clock

Fix the clock enable/disable tracking in the AMBA CLCD driver so
that the driver doesn't try to disable an already disabled clock,
thereby causing the clock (if shared) to become unbalanced.

This resolves a problem with CLCD on LPC32xx ARM platforms.

On PL111, as found on Realview and other platforms, these registers are
always arranged as CNTL then IENB.  On PL110, these registers are IENB
then CNTL, except on Versatile platforms.

Re-arrange the handling of these register swaps so that PL111 always
gets it right without resorting to ifdefs, leaving the only case needing
special handling being PL110 on Versatile.

Fill out amba/clcd.h with the PL110/PL111 register definition
differences in case someone tries to use the PL110 specific definitions
on PL111.

handling of log-levels and newlines") changed printk semantics.  printk
lines with multiple KERN_<level> prefixes are no longer emitted as
before the patch.

<level> is now included in the output on each additional use.
