scripts: sd_fusing_rpi3.sh: add inform partition support

To implement Tizen upgrade solution, reboot parameter should be
delivered into u-boot so that u-boot can jump to proper partition. But,
new SoC on RPI3 does not support any specific registers (e.g., INFORM
register of Exynos) to store reboot parameter upon SW reset.

Add inform partition and make "reboot-param.bin" file for passing reboot
parameter.
