In this patch series, added state checker to validate gamma lut values
for icelake+ platforms. It's extension of the
patch series https://patchwork.freedesktop.org/patch/328246/?series=58039
which enabled the basic infrastructure and state checker for
legacy platforms.
Major changes done in patch 2, details in commit message.

Swati Sharma (3):
  drm/i915/color: Fix formatting issues
  drm/i915/color: Extract icl_read_luts()
  FOR_TESTING_ONLY: Print rgb values of hw and sw blobs

For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.

This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.

Major change done-removal of readouts of coarse and fine segments
because PAL_PREC_DATA register isn't giving propoer values.
State checker limited only to "fine segment"

v2: -readout code for multisegmented gamma has to come
     up with some intermediate entries that aren't preserved
     in hardware (Jani N)
    -linear interpolation (Ville)
    -moved common code to check gamma_enable to specific funcs,
     since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
    -used single lut [Jani N]
    -improved and more readable for loops [Jani N]
    -read values directly to actual locations and then fill gaps [Jani N]
    -moved cleaning to patch 1 [Jani N]
    -renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
     make it similar to icl_load_luts()
    -renamed icl_compute_interpolated_gamma_blob() to
     icl_compute_interpolated_gamma_lut_values() more sensible, I guess
v4: -removed interpolated func for creating gamma lut values
    -removed readouts of fine and coarse segments, failure to read PAL_PREC_DATA
     correctly
