[Intel-gfx] [PATCH v2 1/3] drm/i915: Setup multicast register steering for all gen >= 10

[Matt Roper]

Steering of multicast registers for workarounds is needed on all
platforms gen10 and above.  Move the wa_init_mcr() call to the
higher-level gt_init_workarounds() rather than re-calling it for each
individual platform.
