ipq40xx: fix pcie msi IRQ trigger level
From: Niklas Cassel <niklas.cassel@linaro.org>
|The databook clearly states that the MSI IRQ (msi_ctrl_int) is a level
|triggered interrupt.
|
|The msi_ctrl_int will be high for as long as any MSI status bit is set,
|thus the IRQ type should be set to IRQ_TYPE_LEVEL_HIGH, causing the
|IRQ handler to keep getting called, as long as any MSI status bit is set.
|[...]
|Not having the correct IRQ type defined will cause us to lose interrupts,
|which in turn causes timeouts in the PCIe endpoint drivers.
