Hi,

Found this while debugging an issue with lockups during boot of
Linux on Xen.

In the particular setup, I'm running without EL3 firmware so group0
interrupts are disabled on the physical interface and enabled on the
virtual interface.

Looks like we're checking the wrong CPU_CTLR reg for vCPUs. This fixes
the problem on my side.

Cheers,
Edgar
