Subject: drivers/intel/gma/acpi: Add Kconfigs for backlight registers

Instead of adding more versions of the `*pch.asl`, unify the existing
ones and allow to override the register locations via Kconfig. The
current defaults should work for Skylake and some newer platforms.

TEST=Booted ThinkPad X201s, backlight control still works.
