net: phy: Add support for polling cable test
Some PHYs are not capable of generating interrupts when a cable test
finished. They do however support interrupts for normal operations,
like link up/down. As such, the PHY state machine would normally not
poll the PHY.
Add support for indicating the PHY state machine must poll the PHY
when performing a cable test.
