Convert Amlogic Meson GPIO interrupt controller binding to yaml.
Reviewed-by: Rob Herring <robh@xxxxxxxxxx>

---
- consider that more than one compatible may be set
- remove bus part from example
- remove minItem/maxItem properties for compatible
- reduce compatible fallback complexity

-Amlogic meson GPIO interrupt controller
-
-Meson SoCs contains an interrupt controller which is able to watch the SoC
-pads and generate an interrupt on edge or level. The controller is essentially
-a 256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
-or level and polarity. It does not expose all 256 mux inputs because the
-documentation shows that the upper part is not mapped to any pad. The actual
-number of interrupt exposed depends on the SoC.
-
-Required properties:
-
-- compatible : must have "amlogic,meson8-gpio-intc" and either
- "amlogic,meson8-gpio-intc" for meson8 SoCs (S802) or
- "amlogic,meson8b-gpio-intc" for meson8b SoCs (S805) or
- "amlogic,meson-gxbb-gpio-intc" for GXBB SoCs (S905) or
- "amlogic,meson-gxl-gpio-intc" for GXL SoCs (S905X, S912)
- "amlogic,meson-axg-gpio-intc" for AXG SoCs (A113D, A113X)
- "amlogic,meson-g12a-gpio-intc" for G12A SoCs (S905D2, S905X2, S905Y2)
- "amlogic,meson-sm1-gpio-intc" for SM1 SoCs (S905D3, S905X3, S905Y3)
- "amlogic,meson-a1-gpio-intc" for A1 SoCs (A113L)
- "amlogic,meson-s4-gpio-intc" for S4 SoCs (S802X2, S905Y4, S805X2G, S905W2)
-- reg : Specifies base physical address and size of the registers.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 2.
-- meson,channel-interrupts: Array with the 8 upstream hwirq numbers. These
- are the hwirqs used on the parent interrupt controller.
-
-Example:
-
-gpio_interrupt: interrupt-controller@9880 {
- compatible = "amlogic,meson-gxbb-gpio-intc",
- "amlogic,meson-gpio-intc";
- reg = <0x0 0x9880 0x0 0x10>;
- interrupt-controller;
- #interrupt-cells = <2>;
- meson,channel-interrupts = <64 65 66 67 68 69 70 71>;
