Subject: drm/amd: Extend ROCt to surface UUID for devices that have them
Git-commit: 0c663695a6cb9820692e7e37239c5be90c77b21d
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Devices from Arcturus onwards will have their UUID exposed to Thunk.
Adding neccessary functions to the kernel to propagate the uuid.
