Ville Syrjälä 03b0ce9532 drm/i915: Add support for half float framebuffers for gen4+ primary planes 
gen4+ supports fp16 pixel formats on the primary planes. Add the
relevant code.

On ivb fp16 scanout is slightly busted. The output from the plane will
have 1/4 the expected value. For the primary plane we would have to
use the pipe gamma or pipe csc to correct that which would affect all
the other planes as well, hence we simply choose not to expose fp16
on the ivb primary plane. On hsw the primary plane got fixed.

On gmch platforms I observed that the plane width must be below 2k
pixels with fp16 or else we get a corrupted image. This limitation
does not seem to be documented in bspec. I verified the exact limit
using the chv pipe B primary plane since it has windowing capability.
The stride limits are unaffected by fp16.

v2: Rebase on top of icl fp16
    Split thea gen4+ primary plane bits into a separate patch
    Deal with HAS_GMCH()
