drm/i915: Finish the LUT state checker

Browse source

We have full readout now for all platforms (sans the icl+
multi-segment readout hw fail), so hook up the LUT state
checker for everyone.

We add a new vfunc for this since different platforms need
to handle the details a bit differently.

The implementation is rather repetitive in places. Probably
we want to think of a more declarative approach for the
LUT precision/etc. stuff in the future...

Note that we're currently missing readout for c8_planes, so
we'll have to skip the state check in that case.

v2: Fix readout for C8 use cases
v3: Skip C8 entirely due to lack of c8_planes readout
    Add ilk_has_pre_csc_lut() helper and use other such helpers
