net: dsa: sja1105: register the MDIO buses for 100base-T1 and 100base-TX
The SJA1110 contains two types of integrated PHYs: one 100base-TX PHY
and multiple 100base-T1 PHYs.
The access procedure for the 100base-T1 PHYs is also different than it
is for the 100base-TX one. So we register 2 MDIO buses, one for the
base-TX and the other for the base-T1. Each bus has an OF node which is
a child of the "mdio" subnode of the switch, and they are recognized by
compatible string.
