dt-bindings: interrupt-controller: Convert marvell,ap806-gicp to DT schema 

Convert the Marvell GICP MSI controller binding to schema format. It's a
straight-forward conversion of the typical MSI controller.

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;

};
