bus: ti-sysc: Fix warnings for unbind for serial
We can get "failed to disable" clock_unprepare warnings on unbind at least
for the serial console device if the unbind is done before the device has
been idled.
As some devices are using deferred idle, we must check the status for
pending idle work to idle the device.
Fixes: 76f0f772e469 ("bus: ti-sysc: Improve handling for no-reset-on-init and no-idle-on-init")
