[PATCH 2/2] riscv: dts: spacemit: k3-com260-ifx: add eeprom on i2c1

[Jennifer Berringer]

Enable i2c1 for k3-com260-ifx and use it for a 24c02 eeprom. This
eeprom, unlike the one connected to i2c2, is part of the carrier board.
Some boards do not have any data programmed on this eeprom from factory.
