intel: Fix pixel shader scratch space allocation on Gen9+ platforms.

Browse source 
We had missed a bit of errata - PS scratch needs to be computed as if
there were 4 subslices per slice, rather than 3.

This is a conservative backport of commit aaee3daa90.
It only increases the scratch amount, unlike the original commit which
decreases it on Skylake GT1-3 to avoid overallocating.
