There could be i2c memory on board where you can find out this information but that's
problematic if it is empty or you want to use this i2c for something else.
For all microblaze boards I use XILINX_BOARD_NAME which reflects hw design
(if user is smart enough board name is the part of hw design name).
For zynq/socfpga sensible solution is probably to load this name for DTS.

Thanks,
