usb: dwc3: core: fix order of PM runtime calls
commit fed33afce0eda44a46ae24d93aec1b5198c0bac4 upstream.
Currently, we disable pm_runtime before all register
accesses are done, this is dangerous and might lead
to abort exceptions due to the driver trying to access
a register which is clocked by a clock which was long
gated.
Fix that by moving pm_runtime_put_sync() and pm_runtime_disable()
as the last thing we do before returning from our ->remove()
method.
Fixes: 72246da (usb: Introduce DesignWare USB3 DRD Driver)
