[PATCH 1/2] drm/amd/powerplay: remove the support of xgmi pstate on vega20 from swsmu

[Kevin Wang]

the vega20 asic uses legacy powerplay driver by default.

1. cleanup is_support_sw_smu_xgmi() function.
(ony use for vega20 xgmi pstate check)
2. by default, the vega20 set xgmi pstate by legacy powerplay routine.
