Add New Vendor Seeed to Table of Hardware

[Erik Beck]

Hi,

Could the appropriate admin please add Seeed to the Table of Hardware?

I'd like to start documenting the Seeed LinkStar H68k-1432v1 I have
been working on support for and am preparing a pull request.

Currently there is no entry in the vendor table for Seeed, so I can't
start to create a device entry.

Thanks,

Erik
