This patch adds support for the other three palette formats possible with
the PXA LCD controller. This is required on boards where an LCD is connected
with all its 18 bits. With this patch, it's possible to use an 8-bit mode
with 18-bit palette entries. This used to be possible in 2.4 kernels but
disappeared in 2.6. With current kernels, you can only get wrong colours
out of an LCD connected this way.
Users can choose the palette format by doing something like this
in their board definition:
static struct pxafb_mach_info my_fb_info = {
[...]
.lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3,
.lccr4 = LCCR4_PAL_FOR_2,
[...]
};

Add the ability to have pxafb use only certain fixed video modes
(selected on a per platform basis). This is useful on production
hardware such as the Zaurus cxx00 models where the valid modes are
known in advance and any other modes could result in hardware damage.
Following this, add support for the cxx00 QVGA mode. Mode information
is passed to the lcd_power call to allowing the panel drivers to
configure the display hardware accordingly (corgi_lcd already contains
the functionality for the cxx00 panel).
This mirrors the setup already used by w100fb.

Fix warning:
drivers/video/pxafb.h:119:5: warning: "DEBUG" is not defined
by removing the whole
#if DEBUG
#define DPRINTK(fmt, args...) printk...etc...
#else
#define DPRINTK(fmt, args...)
#endif
stuff - we have pr_debug() for this.

To solve touchscreen interference problems devices like the Sharp Zaurus
SL-C3000 need to know the length of the horitzontal sync pulses. This patch
adds a hook to pxafb so the touchscreen driver can function correctly.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
