drm/i915/display: Add macro to compare gamma hw/sw lut



Add macro to compare hw/sw gamma lut values. First need to
check whether hw/sw gamma mode matches or not. If not
no need to compare lut values, if matches then only compare
lut entries.

v5: -Called PIPE_CONF_CHECK_COLOR_LUT inside if (!adjust) [Jani]
    -Added #undef PIPE_CONF_CHECK_COLOR_LUT [Jani]
v8: -Added check for gamma mode before gamma lut entry comparison
     [Jani]
    -Split patch 3 into 4 patches
