This is a pfn (page-frame number) not a raw address, so we need to
shift it right by 12.

This adds a very simple RTC device and implements reading the time of
day based on the host's time of day. It currently doesn't support
setting the time or wake up alarms but could do so in the future.
Also instantiate it and add the appropriate nodes to the device-tree
for ARM guests.

This fixes an issue on kevin where if we start on a little core, the
kernel doesn't like the generic ARMv8 target cpu type for some reason. To
fix this we must query the preferred type from the vm device first and
supply that to the vcpu init ioctl.
We need to change the signature of the configure_vcpu method to pass
in the vm object even though we aren't using it on x86.

guests right now
- switches both ARMv7 and aarch64 builds to use aarch64 kvm bindings
- adds support for ARMv8 Linux guest with dynamic flattened-device-tree
