[PATCH v12 15/21] PCI: microchip: Add event IRQ domain ops to struct plda_event

For lack of an MSI controller, The new added PCIe interrupts have to be
added to global interrupt event field. PolarFire event domain ops can not
be re-used.

PLDA event domain ops instances will be implemented in later patch.
