drm/i915/icp: Add backlight Support for ICP
ICP has two backlight controllers - similar to previous platforms like
BXT -, but we only use one controller for now, so we can just reuse
the CNP code.
v2: Remove the usage of ICP_SECOND_PPS_BACKLIGHT register.(Jani)
Reuse CNP code since it is very similar.(Ville)
v3 (from Paulo): Rebase.
v4 (from Paulo): adjust commit message (James) and comment (Rodrigo).
