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`.
