usb: typec: ucsi: Schedule connector worker on freezable workqueue

Browse Source 
Currently, the UCSI connector worker is scheduled on the non-freezable
system workqueue. During system suspend, on a plug/unplug event, the
worker can run before the devices have actually resumed. The UCSI
instances can implement operations that might need to do some HW accesses
while the devices are still suspended.

Scheduling the USCI connector worker on the freezable system workqueue
instead will ensure the devices are resumed by the time the worker is
scheduled to run.
