Changes from v5: - Added "interconnect-names" property
Changes from v4: - Squashed a patch to another one to fix Jonathan's comment - Add back the pm_runtime_get_if_in_use() check
Changes from v3: - Rebased on top of Jonathan's patch which adds support for changing gpu freq through hfi on newer targets - As suggested by Rob, left the icc_path intact for pre-a6xx GPUs
