Add RPI 2/3 Firmwares

[nekoprog]

Copy required firmwares for RPI 2/3 to boot properly.

Required packages for building RPI images:

For RPI2
pkg install git qemu-user-static arm-gnueabi-binutils u-boot-rpi2 rpi-firmware

For RPI3
pkg install git qemu-user-static aarch64-binutils u-boot-rpi3 rpi-firmware

We need to add the package hint for rpi-firmware somewhere. Or we could check packages at runtime. Doing something similar for core.git runtime deps: https://github.com/opnsense/core/blob/master/Makefile#L166 (arcane expansion, checks for package installed in other targets...)

Can this check option works if we add some line on device config? If variables can be exported from device config, need to append the list at core.git.

Right, I forgot about other arch build, will fix that with a case later.

Merged, thanks a lot! :)

That's fast! Sure no problem. Will find other way to make the kernel production specific to arm devices.
