The Inter Processor Interrupt is a block part of the SoC, not the
"machine" (talking about machine is borderline with the PMU, since
it is embedded into the ZynqMP SoC, but currentl QEMU doesn't
support multi-arch cores).

Move the IPI state to the SoC state, this will simplify the review
of the next patch.

Seems to be useful for debugging too, since the XlnxZynqMPIPIs'
addresses are not lost after xlnx_zynqmp_pmu_init.
