Indeed, I can relicense it.

Correct, but these are here for other reason - patch 2. These are not
needed for the qcom,board-id property but they will be used by
drivers/soc/qcom/socinfo driver. The values are stored in shared memory
(smem) and accessible/used by Linux, bootloader and firmware. We need to
be sure each define is consistent across different software. Therefore I
consider them values matching bindings.

Best regards,
Krzysztof
