drm: Nuke fb->pixel_format

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

v2: Fix commit message (Laurent)
    Rebase due to earlier removal of many fb->pixel_format uses,
    including the 'fb->format = drm_format_info(fb->format->format);'
    snafu
v3: Adjusted the semantic patch a bit and regenerated due to code
    changes
