board/BuR/common: add 'brdefaulip_setup' function
Many B&R boards are equipped with an I2C-EEPROM where various
information can be stored.
Today there is only a single byte for 'board_id' used.
We write this 'board_id' into environment for later use during boot.
If the value != 0xFF, meaning the byte is programmed, we modify the
"brdefaultip" environment variable for setting an IP-Address based on
board_id.
