gma: Add support for ULX variants
On Haswell and Broadwell, the ULX variants differ only in the available CD clock frequencies and, on Haswell, the maximum DP link rate. On newer generations (Skylake+), they differ only in output buffer tuning.
Also update the PCI IDs from Haswell to Skylake.
Still untested, which was the original reason to skip ULX.

Also update the PCI IDs from Haswell to Skylake.
Still untested, which was the original reason to skip ULX.
