PATCH v2 1/1 ARM: dts: imx6sx: fix irq for pcie bridge

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.
