[PATCH 5/5] riscv: dts: spacemit: k3-com260: Set Ethernet MAC from EEPROM

[Troy Mitchell]

The EEPROM on the K3 CoM260 module stores the board MAC address in its
ONIE TLV data. Assign it to the module's Ethernet controller, so that
every carrier board using the module gets a stable MAC address instead
of a random one.
