Console device handling in bhyve is different for amd64 and arm64.
On amd64, it's configured as an LPC device, and multiple consoles are
supported.

On arm64, only a single console can be configured, and the syntax is
different:

 -o console=/dev/nmdmguest0A

Update the bhyve command generation accordingly.
