generic: fix mediatek and dsa not detecting mac-addr from nvmem

Nvmem require the device node to be registered with the of_platform.
Register the device node so that nvmem can correctly find the dev and
correctly load the mac-addr stored in the nvmem cell declared in the dts.

+Subject: [PATCH 1/2] drivers: net: mediatek: register of_platform for every
+ port
+
+Currently the nvmem framework require the devicenode to be registred on
+the of_platform or of_get_mac_address fail to get the macaddress if
+defined using an nvmem cell. Fix this by registrering these special node
+so they can be found by of_find_device_by_node.

+Subject: [PATCH 2/2] dsa: register every port with of_platform
+
+The declaration of a different mac-addr using the nvmem framework is
+currently broken. The dsa code use the generic of_get_mac_address where
+the nvmem function require the device node to be registred in the
+of_platform to be found by of_find_device_by_node. Register every port
+in the of_platform so they can corrently found and a custom mac-addr can
+correctly be declared using a nvmem-cell declared in the dts.
