When a CPU is hot unplugged, the IPI interrupt source should be
deconfigured and the event queue cleared.

Hi,
Here are a couple of small fixes to support CPU hot unplug. There are
still some issues to be investigated as, in some occasions, after a
couple of plug and unplug, the cpu which was removed receives a 'lost'
interrupt. This showed to be the decrementer under QEMU.
Nevertheless, these patches
When resetting an IPI, hw_ipi should also be set to zero.
