Up to now, subslice mask was assumed to be uniform across slices. But
starting with Cannonlake, slices can be asymmetric (for example slice0
has different number of subslices as slice1+). This change stores all
subslices masks for all slices rather than having a single mask that
applies to all slices.
v2: Rework how we store total numbers in sseu_dev_info (Tvrtko)
Fix CHV eu masks, was reading disabled as enabled (Tvrtko)
Readability changes (Tvrtko)
Add EU index helper (Tvrtko)
v3: Turn ALIGN(v, 8) / 8 into DIV_ROUND_UP(v, BITS_PER_BYTE) (Tvrtko)
Reuse sseu_eu_idx() for setting eu_mask on CHV (Tvrtko)
Reformat debug prints for subslices (Tvrtko)
v4: Change eu_mask helper into sseu_set_eus() (Tvrtko)
