arm: dts: apple: Update Apple M1 device trees

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.
