This commit implements VCN reset capability for SMU v13.0.6 with the following
changes:
1. Added new PPSMC message ID (0x5B) for VCN reset in SMU firmware interface
2. Extended SMU capabilities to include VCN_RESET support
3. Implemented VCN reset support check:
- Added smu_v13_0_6_reset_vcn_is_supported() function
4. Updated SMU v13.0.6 PPT functions to include VCN reset operations
v2: clean up debug info (Alex)
v3: remove unsupported message and split smu v13.0.6 changes to a separate
patch (Lijo)
v4: simply the function (smu_v13_0_6_reset_vcn_is_supported) (Lijo)
