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.

Please cherry-pick it on 4.9.y, 4.4.y and 3.18.y as well.
