arm64: dts: mediatek: mt7986a: add 'soc-uuid' cell to efuse 



The efuse of the MediaTek MT7986 contains an 8-byte unique identifier.
Add a 'soc-uuid' cell covering those 8 bytes to the nvmem defininition
of the efuse to allow easy access from userspace, eg. to generate a
persistent random MAC address on boards like the BananaPi R3 which
doesn't have any factory-assigned addresses.
