[ARM] pxafb: cleanup of the color format manipulation code
1. introduce var_to_depth() to calculate the color depth including the
transparency bit
2. the conversion from 'fb_var_screeninfo' to LCCR3 BPP bits can be re-
used by overlays (in OVLxC1), thus an individual pxafb_var_to_bpp()
has been separated out.
3. pxafb_setmode() should really set the color bitfields correctly at
begining, introduce a pxafb_set_pixfmt() for this
4. allow user apps to specify color formats within fb_var_screeninfo,
and checking of this in pxafb_check_var() has been simplified as
below:
a) pxafb_var_to_bpp() should pass - which means a basically correct
bits_per_pixel and color depth setting
b) the RGBT bitfields are then forced into supported values by
pxafb_set_pixfmt()
