mb/google/glados: port to FSP 2.0

This patch is part of the patch series to drop support for FSP 1.1 in
soc/intel/skylake.

The following modifications have been done to migrate the board(s) from
FSP 1.1 to FSP 2.0:

- remove deprecated devicetree VR_RING domain (only 4 domains in FSP 2.0)
- switch to using the FSP default VBT

TODO:
- testing
