net: phy: motorcomm: Enable optional clock for YT8531

Browse source

Some boards feed the YT8531 PHY from an SoC-provided external
reference clock described by the common ethernet-phy "clocks" property.

Enable the optional PHY clock during probe so boards can model this
clock as a PHY input instead of keeping the clock alive from the MAC
driver.

This is needed on the Alientek DLRV1126, where the PHY reference clock
is provided by CLK_GMAC_ETHERNET_OUT.
