Evan Quan 42c7de9622 drm/amd/pm: revise the driver reloading fix for SMU 13.0.0 and 13.0.7
The current approach breaks S3/S4 as asic reset is needed for them.
And putting SMU out of service(via SMU_MSG_PrepareMp1ForUnload) will make
that(asic reset) failed. Considering with current designs, there is
actually also asic reset involved on driver reloading. That can make
asic back to a clean state. So, the SMU_MSG_PrepareMp1ForUnload operation
will be not so necessary. Thus we will just drop the SMU_MSG_PrepareMp1ForUnload
operation. We may revise the whole driver reloading sequences when there
is a better design.
