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 spacing in set_sseu_info args
use set_sseu_info to initialize sseu data when building
device status in debugfs
rename variables in intel_engine_types.h to avoid checkpatch
warnings
v3: update headers in intel_sseu.h
v4: add const to some sseu_dev_info variables
use sseu->eu_stride for EU stride calculations
v5: address review comments from Tvrtko and Daniele
v6: remove extra space in intel_sseu_get_subslices
return the correct subslice enable in for_each_instdone
add GEM_BUG_ON to ensure user doesn't pass invalid ss_mask size
use printk formatted string for subslice mask
v7: remove string.h header and rebase
