[wip] Add wrapper for device_tree crate, bootup with DTB

This is to easily add necessary functions without touching the original crate - this will probably need to be upstreamed eventually!

Switch on MMU immediately to avoid unaligned access
...
Since enabling armv6 unaligned access bit U in CP15 C1
requires AArch32 assembly and I don't want to introduce
yet another boot stub, I'll just initialize MMU right away
- this causes CPU to treat SCTLR_EL1.A differently and not
cause any alignment faults.
In the future, a small AArch32 boot stub that uses
now commented out fn enable_armv6_unaligned_access()
should be used to set U=1 and A=0 for full unaligned
access even when MMU is off. See ARM documentation
linked from that fn.
