riscv: dts: spacemit: add 24c02 eeprom on BPI-F3
The BPI-F3 board includes a 24c02 eeprom, that stores the MAC addresses
of the two network interfaces and the board's serial number. These
values are also exposed via an onie,tlv-layout nvmem layout.
The eeprom is marked as read-only since its contents are not supposed to
be modified.
