From: Marek Vasut <marex@xxxxxxx>

Describe optional external ethernet RX clock in the DT binding
to fix dtbs_check warnings like:

arch/arm/boot/dts/stm32mp153c-dhcom-drc02.dt.yaml: rcc@50000000: 'assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+'
