drm/format-helper: Rename drm_fb_xrgb8888_to_mono_reversed()
There is no "reversed" handling in drm_fb_xrgb8888_to_mono_reversed():
the function just converts from color to grayscale, and reduces the
number of grayscale levels from 256 to 2 (i.e. brightness 0-127 is
mapped to 0, 128-255 to 1). All "reversed" handling is done in the
repaper driver, where this function originated.
Hence make this clear by renaming drm_fb_xrgb8888_to_mono_reversed() to
drm_fb_xrgb8888_to_mono(), and documenting the black/white pixel
mapping.
