Subject: drm/i915: Introduce gt_init_mmio
Git-commit: d0eb6866879fbd14f798aacfa4379c206249c1a6
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

We already call 2 gt-related init_mmio functions in driver_mmio_probe
and a 3rd one will be added by a follow-up patch, so pre-emptively
introduce a gt_init_mmio function to group them.
