PCI: microchip: Add get_events() callback and add PLDA get_event()
As PLDA dts binding doc(Documentation/devicetree/bindings/pci/
plda,xpressrich3-axi-common.yaml) showes, PLDA PCIe contains an interrupt
controller.
PolarFire implements its own PCIe interrupts, additional to the regular
PCIe interrupts, due to lack of an MSI controller, so the interrupt to
event number mapping is different to the PLDA regular interrupts,
necessitating a custom get_events() implementation.
Microchip Polarfire PCIe additional intrerrupts:
EVENT_PCIE_L2_EXIT
EVENT_PCIE_HOTRST_EXIT
EVENT_PCIE_DLUP_EXIT
EVENT_SEC_TX_RAM_SEC_ERR
EVENT_SEC_RX_RAM_SEC_ERR
....
plda_get_events() adds interrupt register to PLDA local event num mapping
codes. All The PLDA interrupts can be seen in new added graph.
