Marco Franchi 48c926cd34 dt-bindings: Remove leading zeros from bindings notation
Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`

Some unnecessary changes were manually fixed.

Allwinner Sunxi NMI Controller
==============================
Required properties:
- compatible : should be one of the following:
- "allwinner,sun7i-a20-sc-nmi"
- "allwinner,sun6i-a31-sc-nmi" (deprecated)
- "allwinner,sun6i-a31-r-intc"
- "allwinner,sun9i-a80-nmi"
- 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 shall be 2. The first cell is the IRQ number, the
second cell the trigger type as defined in interrupt.txt in this directory.
- interrupt-parent: Specifies the parent interrupt controller.
- interrupts: Specifies the interrupt line (NMI) which is handled by
the interrupt controller in the parent controller's notation. This value
shall be the NMI.
Example:
sc-nmi-intc@1c00030 {
compatible = "allwinner,sun7i-a20-sc-nmi";
interrupt-controller;
#interrupt-cells = <2>;
reg = <0x01c00030 0x0c>;
interrupt-parent = <&gic>;
interrupts = <0 0 4>;
};
