5Required properties:
6
7- compatible: should be "al,alpine-msix"
8- reg: physical base address and size of the registers
9- interrupt-parent: specifies the parent interrupt controller.
10- interrupt-controller: identifies the node as an interrupt controller
11- msi-controller: identifies the node as an PCI Message Signaled Interrupt
12		  controller
13- al,msi-base-spi: SPI base of the MSI frame
14- al,msi-num-spis: number of SPIs assigned to the MSI frame, relative to SPI0

19	compatible = "al,alpine-msix";
20	reg = <0x0 0xfbe00000 0x0 0x100000>;
21	interrupt-parent = <&gic>;
22	interrupt-controller;
23	msi-controller;
24	al,msi-base-spi = <160>;
25	al,msi-num-spis = <160>;
