ks_pcie_msi_irq_handler() invokes ks_pcie_handle_msi_irq() for handling
the interrupts.
Having two functions for handling the interrupt was used when keystone
PCIe driver was implemented using two files but with commit b492aca35c
("PCI: keystone: Merge pci-keystone-dw.c and pci-keystone.c"), which
merged the keystone PCIe driver to use a single file, two functions for
handling the interrupt handler are not required.
Handle MSI interrupt in a single interrupt handler here.
