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.

Add a node for the watchdog timer based on the proposed Linux
device tree bindings.
Remove the old reboot node which was a watchdog timert node in
disguise using a preliminary device tree binding.

Add preliminary device trees for the Apple M1 mini (2020) and
Apple M1 Macbook Pro 13" (2020). Device tree bindings for
the Apple M1 SoC are still being formalized and these device
trees will be synchronized with the Linux kernel as needed.
The device trees in this commit are based on the initial Apple
M1 device trees from Linux 5.13, nodes for dart, pcie, pinctrl,
pmgr, usb based on bindings on track for inclusion in Linux
5.15 and 5.16 and nodes for i2c, mailbox, nvme, pmu, spmi and
watchdog that don't have a proposed binding yet.
These device trees are provided as a reference only as U-Boot
uses the device tree passed by the m1n1 bootloader.
