arm: dart6ul: read and print SoM info from eeprom on startup
The dart6ul has an i2c eeprom at 0x50 which contains, among other
things, the manufacturing/revision/options info of the SoM. This patch
replaces the current checkboard() implementation with a more
exhaustive one based on the content of the eeprom.
Since this code uses the new driver model, some changes were also
required in the DTS to make the nodes related to i2c available before
relocation.
This code was inspired from the supported u-boot code from Variscite
which can be found here:
