net: phy: motorcomm: enable the reference clock for YT8521

Browse Source 
Commit 42310a2438 ("net: phy: motorcomm: Enable optional clock for
YT8531") enables the SoC-provided reference clock for the YT8531 in its
probe. The YT8521 has the same need on crystal-less boards but goes
through yt8521_probe(), so enable it there too. The clock is optional,
so crystal-clocked boards are unaffected.
