drm/amd/pm: apply SMU 13.0.10 workaround during MP1 unload
On SMU v13.0.10, sending PrepareMp1ForUnload with the default
parameter may leave the device in an inaccessible state. This can
affect runtime power management and partial PnP flows.
e.g: kexec, driver unload, boco/d3cold.
Pass the required workaround parameter 0x55, when preparing MP1 for
unload on SMU v13.0.10, keep the existing behavior for other SMU
versions.
