Ville Syrjälä 272725c7db drm: Nuke fb->bits_per_pixel 
Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.
