[Buildroot] [PATCH v2 5/6] boot/beaglev-secondboot: new package

This packages allows to build the first stage bootloader used on the
BeagleV, which is used even before the DDR initialization and
OpenSBI/U-Boot. Yes, "secondboot" is strange for what is the first
stage bootloader, but that's the upstream name.
