[v3 5/5] drm/amd/pm: Add VCN reset message support for SMU v13.0.12

[Jesse.Zhang]

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)
   - PPSMC_MSG_CPPipeReset (0x5F)
   - Updates PPSMC_Message_Count to 0x60 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.
