bhyve: add SMBIOS Baseboard Information

[chuck]

Summary

Add the System Management BIOS Baseboard (or Module) Information
a.k.a. Type 2 structure to the SMBIOS emulation.

Test Plan

Run dmidecode -t 2 and verify output
Also tested against a Linux appliance image with a buggy kernel drive which assumes these values exist

Looks good.

Running the smbiosview command from the EFI shell prompt (non type-2 tables excluded:

Just a comment typo: "number of contained objecct handles" - should be "object".

I noticed this is against the svn repo:

Repository rS FreeBSD src repository - subversion"

You'll probably want to switch over to Git and rebase this patch.

Ah, thanks!

FYI, the repository is wrong because of the .arcconfig in and that 'rS' still references the old svn repository. @lwhsu was going to look at either renaming the rS alias to the git repository, or adding a new alias that could be used in .arcconfig to fix this.

The work was done via git, but I used git-arc for the first time to submit the review. I poked through the script, but didn't find anything that obviously set the repository.

The repository is set implicitly via the .arcconfig file. All my reviews are wrong as well until such time as either .arcconfig or the phab config is changed.
