net: phy: micrel: use generic config_init for KSZ8021/KSZ8031
Use generic config_init callback also for KSZ8021 and KSZ8031.
This has been avoided this far due to commit b838b4aced99 ("phy/micrel:
KSZ8031RNL RMII clock reconfiguration bug"), which claims that the PHY
becomes unresponsive if the broadcast-disable flag is set before
configuring the clock mode.
Turns out that the problem seemingly worked-around by the above
mentioned commit was really due to a hardware-configuration issue, where
the PHY was in fact strapped to address 3 rather than 0.
