[PATCH v2] PCI: j721e: Disable INTx mapping and swizzling

by Siddharth Vadapalli

Since the configuration of INTx (Legacy Interrupt) is not supported, set the .map_irq and .swizzle_irq callbacks to NULL. This fixes the error: of_irq_parse_pci: failed with rc=-22 when the pcieport driver attempts to setup INTx for the Host Bridge via "pci_assign_irq()". The device-tree node of the Host Bridge doesn't contain Legacy Interrupts. As a result, Legacy Interrupts are searched for in the MSI Interrupt Parent of the Host Bridge with the help of "of_irq_parse_raw()". Since the MSI Interrupt Parent of the Host Bridge uses 3 interrupt cells while Legacy Interrupts only use 1, the search for Legacy Interrupts is terminated prematurely by the "of_irq_parse_raw()" function with the -EINVAL error code (rc=-22).
