drivers/intel/gma: Include gfx.asl by default for all platforms...
which select INTEL_GMA_ACPI. Rework brightness level includes and
platform-level asl files to avoid duplicate device definition for GFX0.
Include gfx.asl for Skylake/Kabylake, since all other soc/intel/common
platforms already do. Adjust mb/51nb/x210 to prevent device redefinition.
Some OSes (e.g. Windows, MacOS) require/prefer the ACPI device for
the IGD to exist, even if ACPI brightness controls are not utilized.
This change adds a GFX0 ACPI device for all boards whose platforms
select INTEL_GMA_ACPI without requiring non-functional brightness
controls to be added at the board level.
