net: phy: micrel: fix LAN8814 QSGMII soft reset

LAN8814 QSGMII soft reset was moved into the probe function to avoid
triggering it for each of 4 PHY-s in the package.

However, that broke QSGMII link between the MAC and PHY on most LAN8814
PHY-s, specificaly for us on the Microchip LAN969x switch.
Reading the QSGMII status registers it was visible that lanes were only
partially synced.

It looks like the reset timing is crucial, so lets move the reset back
into the .config_init function but guard it with phy_package_init_once()
to avoid it being triggered on each of 4 PHY-s in the package.
Change the probe function to use phy_package_probe_once() for coma and PtP
setup.
