drm/amd/pm: Add VCN reset message support for SMU v13.0.12
This commit adds support for VCN reset functionality in SMU v13.0.12 by:
1. Adding two new PPSMC messages in smu_v13_0_12_ppsmc.h:
- PPSMC_MSG_ResetVCN (0x5E)
- Updates PPSMC_Message_Count to 0x5F to account for new messages
2. Adding message mapping for ResetVCN in smu_v13_0_12_ppt.c:
- Maps SMU_MSG_ResetVCN to PPSMC_MSG_ResetVCN
These changes enable proper VCN reset handling through the SMU firmware
interface for compatible AMD GPUs.
v2: Added fw version check to support vcn queue reset.
