Since we now have a place (pre_csc_lut) to stuff a purely
internal LUT we can replace glk_load_degamma_lut_linear()
with such a thing and just rely on the normal
glk_load_degamma_lut() to load it as well.
drm_mode_config_cleanup() will clean this up for us.
v2: Pass on the error pointer
Drop a hint about this into the state dump

Since we now have the extra step from hw.(de)gamma_lut into
{pre,post}_csc_lut let's make sure we didn't forget to assign
them appropriately. Ie. basically making sure intel_color_check()
was called when necessary (and that it did its job suitable well).

Rename a few functions from intel_crtc_foo_init() to
intel_foo_crtc_init() so that the namespaec clearly
indicates what feature/file we're talking about.
I left out intel_crtc_crc_init() because the whole crc
stuff uses intel_crtc_ as its namespace currently.

intel_color_init() does both device level and crtc level stuff.
Split it up accordingly.

To reduce the amount of registers written during the vblank evade
critical section let's also split the .color_commit() hook to
noarm+arm pair. The noarm hook runs before the vblank evasion
with the arm hook staying inside the critical section.
Just the framework here, actually moving stuff out into the noarm
hook will follow.

Add func intel_color_lut_equal() to compare hw/sw gamma
lut values. Since hw/sw gamma lut sizes and lut entries comparison
will be different for different gamma modes, add gamma mode dependent
checks.
v3: -Rebase
v4: -Renamed intel_compare_color_lut() to intel_color_lut_equal() [Jani]
-Added the default label above the correct label [Jani]
-Corrected smatch warn "variable dereferenced before check"
[Dan Carpenter]
v5: -Added condition (!blob1 && !blob2) return true [Jani]
v6: -Made patch11 as patch3 [Jani]
v8: -Split patch 3 into 4 patches
-Optimized blob check condition [Ville]
v9: -Exclude spilt gamma mode (bdw and ivb platforms)
as there is exception in way gamma values are written in
hardware [Ville]
-Added exception made in commit [Uma]
-Dropped else, character limit and indentation [Uma]
-Added multi segmented gama mode for icl+ platforms [Uma]
v10: -Dropped multi segmented mode for icl+ platforms [Jani]
-Removed references of sw and hw state in compare code [Jani]
-Dropped inline from func [Jani]

Each platform supports different gamma modes and each gamma mode
has different bit precision. Here bit precision corresponds
to number of bits the hw LUT supports.
Add func per platform to return bit precision corresponding to gamma mode
which will be later used as a parameter in lut comparison function
intel_color_lut_equal().
This is done for legacy, ilk, glk and their variant platforms.
v6: -Added func intel_color_get_bit_precision() to get bit precision for
gamma and degamma lut readout depending upon platform and
corresponding to load_luts() [Ankit]
-Made patch11 as patch3 [Jani]
v7: -Renamed func intel_color_get_bit_precision() to
intel_color_get_gamma_bit_precision()
-Added separate function/platform for gamma bit precision [Ville]
-Corrected checkpatch warnings
v8: -Split patch 3 into 4 separate patches
v9: -Changed commit message, gave more info [Uma]
-Added precision func for icl+ platform
v10: -Removed precision func for chv and icl+ platforms [Jani]
-Added gamma_enable check once [Jani]

Now that we have a new subdirectory for display code, continue by moving
modesetting core code.
display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.
v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
