mfd: syscon: Add Atmel Matrix bus DT binding documentation



The Matrix registers are provided to configure internal bus behavior on
at91 SoCs.
Some registers might be accessed by several drivers (e.g. to configure
external memory bus timings), hence we declare this register set as a
syscon device.

* Device tree bindings for Atmel Bus Matrix

The Bus Matrix registers are used to configure Atmel SoCs internal bus
behavior (master/slave priorities, undefined burst length type, ...)

Required properties:
- compatible:		Should be one of the following
			"atmel,at91sam9260-matrix", "syscon"
			"atmel,at91sam9261-matrix", "syscon"
			"atmel,at91sam9263-matrix", "syscon"
			"atmel,at91sam9rl-matrix", "syscon"
			"atmel,at91sam9g45-matrix", "syscon"
			"atmel,at91sam9n12-matrix", "syscon"
			"atmel,at91sam9x5-matrix", "syscon"
			"atmel,sama5d3-matrix", "syscon"
- reg:			Contains offset/length value of the Bus Matrix
			memory region.

Example:

matrix: matrix@ffffec00 {
	compatible = "atmel,sama5d3-matrix", "syscon";
	reg = <0xffffec00 0x200>;
};
