lib.systems.bluefield2: init

Add support for Nvidia's Bluefield 2 plattform as a compilation
target. There exists a version with and without crypto support,
while the crypto supported version is the most common one.

Support for the non-crypto version can be easily added in the future,
if needed.

For a datasheet of the hardware, see:
