Paul Menzel a8843dee58 Use more secure HTTPS URLs for coreboot sites
The coreboot sites support HTTPS, and requests over HTTP with SSL are
also redirected. So use the more secure URLs, which also saves a
request most of the times, as nothing needs to be redirected.

Run the command below to replace all occurences.

```
$ git grep -l -E 'http://(www.|review.|)coreboot.org'
| xargs sed -i 's,http://\(.*\)coreboot.org,https://\1coreboot.org,g'
```
