Device profile for TC7210

[Nik014]

Hi and thank you for making bcm2-utils :) I've recently acquired a Technicolor TC7210 and I've been playing around with it for a bit. I've managed to write a draft device profile for it, but I could use your help finishing it up before submitting a pull request, if you'd be willing to walk me through the next steps.

I've got eCos console access through 192.168.100.1 and Linux console access (it's borked at the moment, but hopefully it'll be fixed soon). I've also made a bcm2-utils AUR package for Arch-based distros, if you want to include that in your README.md :)

Here are the logs from the eCos console: tc7210_flash_open.txt tc7210_flash_show.txt tc7210_version.txt
