[Intel-gfx] [PATCH 6/8] drm/i915/icp: Add backlight Support for ICP

[Paulo Zanoni]

From: Anusha Srivatsa <anusha.srivatsa at intel.com>

ICP has two backlight controllers - similar to previous platforms like
BXT.

v2: Remove the usage of ICP_SECOND_PPS_BACKLIGHT register.(Jani)
Reuse BXT code since it is very similar.(Ville)

v3 (from Paulo): Rebase.
