package/versal-firmware: new package

This patch adds support for downloading versal microblaze firmware binaries.
These are necessary for booting Xilinx versal devices.

The location of these binaries is temporary, and will soon be added to the
Xilinx firmware repository.  The temporary location is using the same free
distribution license as the Xilinx firmware repository.

Once these files are available on the Xilinx repository, this package will
be updated to the new location.
