[PATCH net-next 4/7] net: freescale: ucc_geth: Fix WOL configuration

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

The get/set_wol ethtool ops rely on querying the PHY for its WoL
capabilities, checking for the presence of a PHY and a PHY interrupts
isn't enough. Address that by cleaning up the WoL configuration
sequence.
