drm/amdgpu: correct the S3 abort check condition
In the normal S3 entry, the TOS cycle counter is not
reset during BIOS execution the _S3 method, so it doesn't
determine whether the _S3 method is executed exactly.
Howerver, the PM core performs the S3 suspend will set the
PM_SUSPEND_FLAG_FW_RESUME bit if all the devices suspend
successfully. Therefore, drivers can check the
pm_suspend_global_flags bit(1) to detect the S3 suspend
abort event.
