[Intel-gfx] [PATCH] drm/i915: Correct ss -> steering calculation for pre-Xe_HP platforms

[Matt Roper]

Accidental use of a "SLICE" macro where a "SUBSLICE" macro was intended
causes the group ID for steering to be calculated incorrectly on
pre-Xe_HP platforms.

Fixes: 9a92732f040a ("drm/i915/gt: Add general DSS steering iterator to intel_gt_mcr")
