rGe72c41772352: arm: Use the correct irq when in the hypervisor

Summary

When booting in the hypervisor state we need to use the hypervisor
interrupt in the generic timer. In this case the registers we access
in the kernel are remapped to the EL2 versions, however this causes
an unexpected interrupt to trigger.
