arm: Clear virtual GICs before handing them over to Linux during setup

Previous users of the virtual GICs may have left them with pending
interrupts or raised priority levels. Fix this up before starting Linux
under Jailhouse control. Otherwise we risk to inject spurious interrupts
or stall interrupt delivery to Linux.
