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. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>
