dt-bindings: mfd: atmel,at91sam9260: Convert to YAML schema

Browse Source 
Changes during conversion:

Add a missing fallback `atmel,at91sam9x5-matrix` for
`microchip,sam9x60-matrix` which is not defined in the text binding.

title: Microchip AT91 Bus Matrix
maintainers:

description:
The Bus Matrix (MATRIX) implements a multi-layer AHB, based on the
AHB-Lite protocol, that enables parallel access paths between multiple
masters and slaves in a system, thus increasing the overall bandwidth.

* 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"
"microchip,sam9x60-matrix", "syscon"
"microchip,sam9x7-matrix", "atmel,at91sam9x5-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>;
};
