treewide: backport support for nvmem on non platform devices

Browse Source 
In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.

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.
