MTL onwards Degamma LUT/PRE-CSC LUT precision has been increased from
16 bits to 24 bits. Currently, drm framework only supports LUTs up to 16
bit precision. Until a new uapi comes along to support higher bitdepth,
upscale the values sent from userland to 24 bit before writing into the
HW to contin
For MTL and beyond, convert back the 24 bit lut values
read from HW to 16 bit values to maintain parity with
userspace values. This way we avoid pipe config mismatch
for pre-csc lut values.

With change [1], visibility of struct seq_file is lost in
intel_display_power.h leading to build errors. Add header
file explicitly to restore visibility.
