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



Changes during conversion:

The text binding is misleading, add a fallback `atmel,at91sam9260-gpbr`
for both `microchip,sam9x60-gpbr` and `microchip,sam9x7-gpbr` which is
missing in old binding and `microchip,sam9x60-gpbr` is not a fallback
for `microchip,sam9x7-gpbr`.

* Device tree bindings for Atmel GPBR (General Purpose Backup Registers)



The GPBR are a set of battery-backed registers.



Required properties:

- compatible:		Should be one of the following:

			"atmel,at91sam9260-gpbr", "syscon"

			"microchip,sam9x60-gpbr", "syscon"

			"microchip,sam9x7-gpbr", "microchip,sam9x60-gpbr", "syscon"

- reg:			contains offset/length value of the GPBR memory

			region.



Example:



gpbr: gpbr@fffffd50 {

	compatible = "atmel,at91sam9260-gpbr", "syscon";

	reg = <0xfffffd50 0x10>;

};
