drm/i915/vlv: use per-pipe backlight controls v2
With the connector and pipe passed around, we can now set the backlight
on the right pipe on VLV/BYT.
v2: drop combination mode check for VLV (Jani)
add save/restore code for VLV backlight regs (Jani)
check for existing modulation freq when initializing backlight regs (Jani)
