Subject: [PATCH v2 1/1] ARM: dts: aspeed-g6: add aliases for mdio nodes

Add aliases for mdio nodes so that we can use name to lookup the
bus address of Aspeed SOC.

For example:
root@...tchley:~# cat /sys/firmware/devicetree/base/aliases/mdio0
/ahb/mdio@...50000
root@...tchley:~# cat /sys/firmware/devicetree/base/aliases/mdio1
/ahb/mdio@...50008
root@...tchley:~# cat /sys/firmware/devicetree/base/aliases/mdio2
/ahb/mdio@...50010
root@...tchley:~# cat /sys/firmware/devicetree/base/aliases/mdio3
/ahb/mdio@...50018
