rockchip: theobroma-systems: migrate git URLs to HTTPS

It turns out only Puma had a working git:// URL. Though that is now
fixed, having HTTPS URLs make it easier to directly reach our cgit
webserver to check what's up without having to change the URL manually.

Depending on your terminal settings, this also makes it possible to
open the link from it.
