3Required properties:
4 - compatible: "atmel,at91sam9263-ac97c"
5 - reg: Address and length of the register set for the device
6 - interrupts: Should contain AC97 interrupt
7 - ac97-gpios: Please refer to soc-ac97link.txt, only ac97-reset is used
8Optional properties:
9 - pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt
