nb/intel/sandybridge: Fill in acpi_name

Browse Source 
Fill in acpi_name to return proper ACPI names. To be used with
SSDT generators.

The ACPI names have to match those already used in ASL code.
By providing the ACPI name it can be retrieved by the
acpi_device_name() method and doesn't need to be hardcoded in
SSDT generators any more.

GFX0 is used in drivers/intel/gma/acpi/pch.asl.
MCHC is used in nb/intel/sandybridge/acpi/hostbridge.asl.
