[PATCH 00/11] Refactor to expand subslice mask (rev 2)

Better match what is presented to userspace through the
I915_QUERY_TOPOLOGY_INFO ioctl. The index into this array is
then calculated:
slice * subslice stride + subslice index / 8

Note this is the second iteration of an original patch to implement
the same. There are a couple of minor code changes based on changes
since the first series was posted. Additionally, the original patch
has been split into several smaller patches with more isolated
changes based on review feedback in that first series.

v2: Fix 32-bit build
v3: Fix typo in haswell sseu info routine and fix SSEU workaround
print
v4: Merge patch to HSW in previous revision with patch to
set subslice_mask for each platform and address feedback
from Chris
v5: No changes in code. Resending due to unrelated failures - confirmed
no failures with trybot.
v6: Minor change in intel_workarounds.c to use the new helper function
v7: Split set sublice function into multiple more manageable patches
And add a couple of GEM_BUG_ON checks requested by Chris
v8: Address new comments from Chris including adding/moving
a couple of ss/eu_stride checks to those previously reviewed
patches earlier in this series
v9: Use memcpy to set subslices (Chris)
