net: phy: Validate PHY LED OPs presence before registering

Validate PHY LED OPs presence before registering and parsing them.
Defining LED nodes for a PHY driver that actually doesn't supports them
is redundant and useless.

It's also the case with Generic PHY driver used and a DT having LEDs
node for the specific PHY.

Skip it and report the error with debug print enabled.
