drm/i915: Expand subslice mask
Currently, the subslice_mask runtime parameter is stored as an
array of subslices per slice. Expand the subslice mask array to
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
v2: Fix 32-bit build
v3: Use new helper function in SSEU workaround warning message
v4: Use GEM_BUG_ON to force developers to use valid SSEU configurations
per platform (Chris)
