ARM: arm-soc Marvell Orion device-tree updates

Browse Source 
This branch contains a set of device-tree conversions for Marvell Orion
 platforms that were staged early but took a few tries to get the branch
 into a format where it was suitable for us to pick up.
 
 Given that most people working on these platforms are hobbyists with
 limited time, we were a bit more flexible with merging it even though
 it came in late.

* Marvell Orion Interrupt controller
Required properties
- compatible : Should be "marvell,orion-intc".
- #interrupt-cells: Specifies the number of cells needed to encode an
interrupt source. Supported value is <1>.
- interrupt-controller : Declare this node to be an interrupt controller.
- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
One entry in the list represents 32 interrupts.
Example:
intc: interrupt-controller {
compatible = "marvell,orion-intc", "marvell,intc";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0xfed20204 0x04>,

- reg : Address and length of the register set for controller.
- gpio-controller : So we know this is a gpio controller.
- ngpio : How many gpios this controller has.
