drm/amd/pm: fix Navi1x runtime resume failure V2
The RLC was put into a wrong state on runtime suspend. Thus the RLC
autoload will fail on the succeeding runtime resume. By adding an
intermediate PPSMC_MSG_PrepareMp1ForUnload(some GC hard reset involved,
designed for PnP), we can bring RLC back into the desired state.
V2: integrate INTERRUPTS_ENABLED flag clearing into current
mp1 state set routines
