drm/i915: Add support for half float framebuffers for ivb+ sprites
ivb+ supports fp16 pixel formats on the sprite planes planes. Expose
that capability.
On ivb/hsw fp16 scanout is slightly busted. The output from the plane
will have 1/4 the expected value. For the sprite plane we can fix that
up with the plane gamma unit. This was fixed on bdw.
v2: Rebase on top of icl fp16
Split the ivb+ sprite birs into a separate patch
v3: Move ivb_need_sprite_gamma() check one level up so that
we don't waste time programming garbage into he gamma registers
