drm/amdgpu: add SPI idle check for GC 9.4.4 in gfx_v9_4_3_is_idle()
GC 9.4.4 uses SPI busy status for idle detection instead of GRBM GUI_ACTIVE.
Add version check to use SPI_BUSY for 9.4.4 while keeping GRBM_STATUS
GUI_ACTIVE check for other GC versions.
v2: move this check into amdgpu_ptl_perf_monitor_ctrl(Lijo)
