drm/i915: clean up plane bpp confusion
- There is no 16bpc linear color format in our hw. gen4+ has a 16 bpc
float layout, but we don't really support it.
- 10bpc is a gen4+ feature, fix up the support for it.
- Update_plane should never see a wrong fb bpp value, BUG in the
corresponding cases.
v2: Rebase on top of Ville's plane pixel layout changes.
v3: Actually drop the old gen4 check for 10bpc planes, spotted
by Ville Syrjälä.
