Subject: [PATCH v2 0/3] riscv: dts: spacemit: add 24c02 eeprom on BPI-F3

The BPI-F3 board has a 24c02 eeprom connected to the i2c bus #2. It
holds board data. This patchset adds support for it.

Version 2 incorporates changes suggested during review of v1.

Changes between version 1 and version 2:
 - Rename i2c2-0-cfg and i2c2-0-pins into i2c2-4-cfg and i2c2-4-pins to match
   the naming convention encoding the function number in the second cell.
 - Rename the 24c02 supply name label to buck3_1v8
 - Add a onie,tlv-layout nvmem layout describing the content of the 24c02 eeprom
