adding the VM-Exit method for Arm64
On amd64, it uses 'HLT' to leave the guest.
Unlike amd64, arm64 can only uses mmio_exit/psci to leave the guest.
So, I designed the HYPERCALL_VMEXIT to be compatible with amd64/arm64.
To keep it simple, I used the address of exception table as the
MMIO base address, so that I can trigger a MMIO-EXIT by forcibly writing this space.
Then, in host user space, I can calculate this address to find out
which hypercall.
