7d9cff3d23 Add psci for arm64. This is currently used when rebooting and powering off 
in qemu.

e5acd89c78 Bring in the start of the arm64 kernel. 
This is only the minimum set of files needed to boot in qemu. As such it is
missing a few things.

The bus_dma code is currently only stub functions with a full implementation
from the development tree to follow.

The gic driver has been copied as the interrupt framework is different. It
is expected the two drivers will be merged by the arm intrng project,
however this will need to be imported into the tree and support for arm64
would need to be added.

This includes code developed by myself, SemiHalf, Ed Maste, and Robin
Randhawa from ARM. This has been funded by the FreeBSD Foundation, with
early development by myself in my spare time with assistance from Robin.

46f52b028f Split out the _acq and _rel functions. These were the same, but there is 
no need for them to be this strong, we only need to provide one or the
other.

While here replace atomic_load_acq_* and atomic_store_rel_* with a single
instruction version, and fix the definition of atomic_clear_* to point to
the correct functions.

23f518054b Add space for future expansion [1]. While here clean up a little, spsr is 
only 32-bits, and mark the holes in the struct with a pad member.

147b9d0418 Add more arm64 machine dependent headers. With this we now have the minimum 
set of machine headers needed to build the userland toolchain.
