arm64: dts: mediatek: mt7981b: add 'soc-uuid' cell to efuse 



The efuse of the MediaTek MT7981 contains a 16-byte unique identifier.
Add a 'soc-uuid' cell covering those 16 bytes to the nvmem defininition
of the efuse to allow easy access from userspace, eg. to generate a
persistent random MAC address on boards which don't have any
factory-assigned addresses.
