dt-bindings/interrupt-controller: Add DT binding for the Marvell GICP 



This commit adds the Device Tree binding documentation for the Marvell
GICP, an extension to the GIC that allows to trigger GIC SPI interrupts
using memory transactions. It is used by the ICU unit in the Marvell
CP110 block to turn wired interrupts inside the CP into SPI interrupts
at the GIC level in the AP.

Marvell GICP Controller

-----------------------



GICP is a Marvell extension of the GIC that allows to trigger GIC SPI

interrupts by doing a memory transaction. It is used by the ICU

located in the Marvell CP110 to turn wired interrupts inside the CP

into GIC SPI interrupts.



Required properties:



- compatible: Must be "marvell,ap806-gicp"



- reg: Must be the address and size of the GICP SPI registers



- marvell,spi-ranges: tuples of GIC SPI interrupts ranges available

  for this GICP



- msi-controller: indicates that this is an MSI controller



Example:



gicp_spi: gicp-spi@3f0040 {

	compatible = "marvell,ap806-gicp";

	reg = <0x3f0040 0x10>;

	marvell,spi-ranges = <64 64>, <288 64>;

	msi-controller;

};
