PHYs on the subboard could not be reached via remote access. But this is
the latest DTS snipplet with some fixes suggested by Geert as a starting

Change since v1:

* new patch
* removed rxc-skew-ps property
* renamed phy-addresses to 0 ('@0')
* dropped '_tx' suffix from 'pins_mii' config
* added 'okay' status
* moved entries to Falcon CPU dtsi

Thanks for the update!
