drm/format-helper: Add generic conversion to 24-bit formats

Browse source

Add drm_fb_xfrm_line_32to24() to implement conversion from 32-bit
pixels to 24-bit pixels. The pixel-conversion is specified by the
given callback parameter. Mark the helper as always_inline to avoid
overhead from function calls.

Then implement all existing line-conversion functions with the new
generic call and the respective pixel-conversion helper.
