drm/i915: Use subslice stride to set subslices for a given slice
Add a subslice stride calculation when setting subslices. This
aligns more closely with the userspace expectation of the subslice
mask structure.
v2: Use local variable for subslice_mask on HSW and
clean up a few other subslice_mask local variable
changes
v3: Add GEM_BUG_ON for ss_stride to prevent array overflow (Chris)
Split main set function and refactors in intel_device_info.c
into separate patches (Chris)
v4: Reduce ss_stride size check when setting subslices per slice
based on actual expected max stride (Chris)
Move that GEM_BUG_ON check for the ss_stride out to the patch
which adds the ss_stride
v5: Use memcpy instead of looping through each stride index
