drm/color-mgmt: Prepare for RGB332 palettes
Add helper drm_crtc_fill_palette_332(), which fills palettes with
RGB332 color data. Each color in RGB332 format serves as an index
into an 8-bit palette that stores the corresponding component-based
colors.
Vesadrm will use the new helper to emulate RGB formats on top of
framebuffers in C8 format.
v2:
- add comments on bit operations (Javier)
