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.
