arm64/vmm: Handle VM_EXITCODE_SUSPENDED This is required for bhyve reboot to work. In particular, unless we suspend vcpu threads here, vm_reinit() will fail with EBUSY. The implementation is copied from amd64; in the not-too-distant future the amd64 and arm64 copies of vmm.c and vmm_dev.c will be merged, so for now it's useful to minimize diffs between amd64 and arm64.

Import the kernel parts of bhyve/arm64 To support virtual machines on arm64 add the vmm code. This is based on earlier work by Mihai Carabas and Alexandru Elisei at University Politehnica of Bucharest, with further work by myself and Mark Johnston. All AArch64 CPUs should work, however only the GICv3 interrupt controller is supported. There is initial support to allow the GICv2 to be supported in the future. Only pure Armv8.0 virtualisation is supported, the Virtualization Host Extensions are not currently used. With a separate userspace patch and U-Boot port FreeBSD guests are able to boot to multiuser mode, and the hypervisor can be tested with the kvm unit tests. Linux partially boots, but hangs before entering userspace. Other operating systems are untested.
