usb: typec: ucsi: Resume in separate work

Browse source

commit e0dced9c7d upstream.

It can take more than one second to check each connector
when the system is resumed. So if you have, say, eight
connectors, it may take eight seconds for ucsi_resume() to
finish. That's a bit too much.

This will modify ucsi_resume() so that it schedules a work
where the interface is actually resumed instead of checking
the connectors directly. The connections will also be
checked in separate tasks which are queued for each connector
separately.
