  The rzn1-gmac instance is connected to a PCS (MIIC). In order to use
this pcs, add support in the sttmac driver to set a generic phylink pcs
device instead of the xpcs only. Moreover, it adds support to provide
a phylink pcs device from the stmmac platform data and use it with the
driver. It also adds the bindings and the new rzn1-gmac driver that
retrieve this pcs from the device-tree.

---
V2:
 - Remove patch that moves phylink_start() earlier in init
 - Add miic_early_qsetup()  which allows initializing some miic port
   earlier to provide a RX clock to stmmac IP
 - Call miic_early_setup() in rzn1 stmmac driver
 - Fix bindings
