The SJA1110 switch uses the mdios property for its two MDIO buses. Instead
of a pattern, define two mdio nodes. This ensures the same compatible
string won't be used twice. The address and size cell definitions can also
be removed now that the reg property has become unnecessary.
Move the comment to the description of mdios, mdio0, and mdio1 properties.
Disallow the mdios property for SJA1105. Require at least one of the MDIO
buses to be defined to prevent empty mdios child node.
