commit 1bcfe0564044be578841744faea1c2f46adc8178 upstream.
Use the correct IRQ line for the MSI controller in the PCIe host controller. Apparently a different IRQ line is used compared to other i.MX6 variants. Without this change MSI IRQs aren't properly propagated to the upstream interrupt controller.
