xen/arm: domain_build: Black list devices using PPIs

Currently, the vGIC is not able to cope with hardware PPIs routed to guests.
One of the solutions to this problem is to skip any device that uses PPI
source completely while building the domain itself.

This patch goes through all the interrupt sources of a device and skip it
if one of the interrupts sources is a PPI. It fixes XEN boot on i.MX8MQ by
skipping the PMU node.
