drm/i915: Add macro for SSEU stride calculation
Subslice stride and EU stride are calculated multiple times in
i915_query. Move this calculation to a macro to reduce code duplication.
v2: update headers in intel_sseu.h
v3: use GEN_SSEU_STRIDE for stride calculations in intel_sseu.h
apply s/bits/max_entries/ to GEN_SSEU_STRIDE parameter
