intel/dev: Implement DG2 restrictions requiring additional DSSes to be disabled.
Note that this causes a geometry slice to be disabled if any DSS is
fused off within that slice, which may seem stricter than the BSpec
quotation implies, but testing shows that pixel pipes with any faulted
DSS don't work at all, and that using a slice with any faulted pixel
pipe leads to serious graphics corruption.
It would be better to query this geometry topology information from
the hardware instead of trying to reconstruct it here, but the kernel
interface for that is not available yet.
