Subject: drm/amdgpu: Add DMCUB to firmware query interface
Git-commit: 976e51a7c0827a870fa08df6ee0a74e937ebbbd9
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The DMCUB firmware version can be read using the AMDGPU_INFO ioctl
or the amdgpu_firmware_info debugfs entry.
