PCI: dwc: Convert struct pcie_port.msi_irq to an array
The Qualcomm DWC PCIe controller supports more than 32 MSI interrupts, but
they are routed to separate interrupts in groups of 32 vectors. To support
this configuration, change the msi_irq field to an array. Let the DWC core
handle all interrupts that were set in this array.
[bhelgaas: reorder, drop "irq" temporary to make patch cleaner]
