net: phy: micrel: allow usage of generic ethernet-phy clock
The generic ethernet-phy binding allows describing an external clock since
commit 350b7a258f20 ("dt-bindings: net: phy: Document support for external PHY clk")
for cases where the phy is not supplied by an oscillator but instead
by a clock from the host system.
And the old named "rmii-ref" clock from 2014 is only specified for phys
of the KSZ8021, KSZ8031, KSZ8081, KSZ8091 types.
So allow retrieving and enabling the optional generic clock on phys that
do not provide a rmii-ref clock.
