vendorcode/amd: Hook up opensil

OpenSIL has a native buildsystem using meson and configuration mechanism
using kconfiglib.

To be able to use the coreboot toolchain with opensil, meson crossfiles
are used, which get generated by coreboot makefiles.

Configuration of opensil is done in a similar fashion with a template
defconfig after which kconfiglib is called to generate headers.
