Subject: [PATCH 5/5] ARM: dts: NSP: Fix MX65 MDIO mux warnings

Firstly this fixes the following message:
mdio-mii-mux: $nodename:0: 'mdio-mii-mux' does not match '^mdio-mux[\\-@]?'

Secondly, move the mdio-mux to within the axi node and add the unit
address. This requires exposing the axi node via a label in bcm-nsp.dtsi.
This fixes the following warning:
Warning (unit_address_vs_reg): /mdio-mii-mux: node has a reg or ranges property, but no unit name
