Subject[PATCH v3 12/18] usb: phy: Probe phy devices on demand
Date
When looking up a phy through its OF node, probe it if it hasn't
already.

The goal is to reduce deferred probes to a minimum, as it makes it very
cumbersome to find out why a device failed to probe, and can introduce
very big delays in when a critical device is probed.
