snb supports fp16 pixel formats on the sprite planes. Expose that
capability. Nothing special needs to be done, it just works.

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

skl+ supports fp16 pixel formats on all universal planes. Add the
necessary bits to expose that capability. The main different to
icl is that we can't scale fp16, so need to add the relevant

Various pixel formats and plane scaling impose additional constraints
on the cdclk frequency. Provide a new plane->min_cdclk() hook that
will be used to compute the minimum acceptable cdclk frequency for
each plane.
Annoyingly on some platforms the numer of active planes affects
this calculation so we must also toss in more planes into the
state when the number of active planes changes.
The sequence of state computation must also be changed:
1. check_plane() (updates plane's visibility etc.)
2. figure out if more planes now require update min_cdclk
computaion
3. calculate the new min cdclk for each plane in the state
4. if the minimum of any plane now exceeds the current
logical cdclk we recompute the cdclk
4. during cdclk computation take the planes' min_cdclk into
accoutn
5. follow the normal cdclk programming to change the
cdclk frequency. This may now require a modeset (except
on bxt/glk in some cases), which either succeeds or
fails depending on whether userspace has given
us permission to perform a modeset or not.
v2: Fix plane id check in intel_crtc_add_planes_to_state()

I forgot to update the g4x sprite scaling stride check when GTT
remapping was introduced. The stride of the original framebuffer
is irrelevant when remapping is used and instead we want to check
the stride of the remapped view.
Also drop the duplicate width_bytes check. We already check that
a few lines earlier.

Split the format lists for different planes on skl/icl more cleanly.
On skl+ we have just two types of planes: those can do planar and
those that can't.
On icl we have three types of planes: hdr planes, sdr planes that
can do planar, and sdr planes that can't do planar. Those latter two
are the same set of planes we must when choose from when picking the
UV vs. Y plane for planar scanout. So we shall just designate
them sdr uv planes and sdr y planes.
