MALI: bifrost: disable regulator when pm status is suspended

Browse Source 
The system calls pm_runtime_get_noresume() to prevent device
from entering to runtime suspend status when reboot, and the
pm_runtime_put_sync_suspend() is called in a delay work,
so when reboot the power domain may be power on,
but the regulator is disabled, it's not allowed.
