usb: typec: tipd: Use read_power_status function in probe

We need the initial power status to be able to reliably detect connector
changes once we introduce de-bouncing for CD321x next. read_power_status
takes care of this and also forwards the status to the trace subsystem
so let's use that instead of open-coding it inside probe.
