Subject: [PATCH 2/2] drm/amd/pm: Use BACO reset arg 0 on XGMI configuration

With arg 1 BACO reset, it will try to reload the SMU FW after reset.
This might failed if driver already in a pending reset status during probe period.
Arg 0 reset will bring  asic back to a clean state and driver will re-init everythign including SMU FW
