net: phy: micrel_ksz90x1: switch to use ofnode apis

phydev->node is phy node, phydev->dev->node is controller
and that current code is likely reading the properties from
controller node and not from phy. So, Use PHY API phy_get_ofnode()
helper to get PHY DT node and use ofnode_read_u32_default() to
read properties in phy node.
