Calling runtime pm APIs pm_runtime_put_sync() and pm_runtime_get_sync()
for enabling/disabling the clocks, sysconfig settings.
Enable clock, configure no-idle/standby when active and configure force idle/standby
and disable clock when idled. This is taken care by the runtime framework when
driver calls the pm_runtime_get_sync and pm_runtime_put_sync APIs.
Need to configure MUSB into force standby and force idle mode when usb not used
