This synchronizes the device trees with those that are in the process of being upstreamed into Linux. This is mostly the current state of the device trees on the asahilinux branch with a few extra bits used by OpenBSD. This includes device trees for machines that were still missing. There are still some differences that will hopefully be resolved soon.
