drm/amd: Fix shutdown (again) on some SMU v13.0.4/11 platforms

Browse Source 
commit 267cace556e8a53d703119f7435ab556209e5b6a upstream.

commit cd94d1b182d2 ("dm/amd/pm: Fix problems with reboot/shutdown for
some SMU 13.0.4/13.0.11 users") attempted to fix shutdown issues
that were reported since commit 31729e8c21ec ("drm/amd/pm: fixes a
random hang in S4 for SMU v13.0.4/11") but caused issues for some
people.

Adjust the workaround flow to properly only apply in the S4 case:
-> For shutdown go through SMU_MSG_PrepareMp1ForUnload
-> For S4 go through SMU_MSG_GfxDeviceDriverReset and
   SMU_MSG_PrepareMp1ForUnload
