The privileged message send and clear instructions (msgsndp & msgclrp)
are privileged, but will generate a hypervisor facility unavailable
exception if not enabled in the HFSCR and executed in privileged
non-hypervisor state.
Add checks when accessing the DPDES register and when using the
msgsndp and msgclrp isntructions.
