drm/i915: Add subslice stride runtime parameter

Browse source

Add a new parameter, ss_stride, to the runtime info
structure. This is used to mirror the userspace concept
of subslice stride, which is a range of subslices per slice.

This patch simply adds the definition and updates usage
in the QUERY_TOPOLOGY_INFO handler.

v2: Add GEM_BUG_ON to make sure ss_stride is valid
