nb/intel/gm45: Simplify GMA SSDT generator
Simplify generation of GMA SSDT, using updated naming convention. If acpi_fill_ssdt is being invoked, then we know the IGD device is present and enabled, so we can skip those checks. And the SSDT generator now checks that the gfx struct is populated, so we can skip that too.
