irqchip: armada-370-xp: implement MSI support
This commit introduces the support for the MSI interrupts in the armada-370-xp interrupt controller driver. It registers an MSI chip to the MSI chip registry, which will be used by the Marvell PCIe host controller driver. The MSI interrupts use the 16 high doorbells, and are therefore notified using IRQ1 of the main interrupt controller.
