PATCH 1/1 dt-bindings: interrupt-controller: Convert al,alpine-msix to DT schema

Convert the Amazaon Alpine MSIX controller binding to schema format.

Drop the interrupt-controller property as the MSIX controller doesn't provide interrupts. The interrupt-parent property is required in this case for custom MSI mapping properties.

-Alpine MSIX controller
-
-See arm,gic-v3.txt for SPI and MSI definitions.
-
-Required properties:
-
-- compatible: should be "al,alpine-msix"
-- reg: physical base address and size of the registers
-- interrupt-controller: identifies the node as an interrupt controller
-- msi-controller: identifies the node as an PCI Message Signaled Interrupt
-		  controller
-- al,msi-base-spi: SPI base of the MSI frame
-- al,msi-num-spis: number of SPIs assigned to the MSI frame, relative to SPI0
-
-Example:
-
-msix: msix {
-	compatible = "al,alpine-msix";
-	reg = <0x0 0xfbe00000 0x0 0x100000>;
-	interrupt-parent = <&gic>;
-	interrupt-controller;
-	msi-controller;
-	al,msi-base-spi = <160>;
-	al,msi-num-spis = <160>;
