[v3,15/18] phy: core: Probe phy providers on demand

Commit Message

When looking up a phy provider 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.
