Subject: [PATCH net-next v3 1/2] dt-bindings: mt76: support setting per-band
MAC address
Introduce support for setting individual per-band MAC addresses using
NVMEM cells by adding a 'bands' object with enumerated child nodes
representing the 2.4 GHz, 5 GHz and 6 GHz bands.
In case it is defined, call of_get_mac_address for the per-band child
node, otherwise try with of_get_mac_address on the main device node and
fall back to a random address like it used to be.
While at it, add MAC address related properties also for the main node.

Changes since v2:
* drop items list with only a single item
