Let's replace the assortment of intel_gt_* and intel_uncore_* functions that operate on MCR registers with a cleaner set of interfaces:
* intel_gt_mcr_read -- unicast read from specific instance * intel_gt_mcr_read_any[_fw] -- unicast read from any non-terminated instance * intel_gt_mcr_unicast_write -- unicast write to specific instance * intel_gt_mcr_multicast_write[_fw] -- multicast write to all instances
We'll also replace the historic "slice" and "subslice" terminology with "group" and "instance" to match the documentation for more recent platforms; these days MCR steering applies to more types of replication than just slice/subslice.
