Convert old text based binding to json 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`.
