[PATCH] ARM: at91: dts: add AC97 support for AT91SAM9G45

[Dmitry Rezvanov]

Hi, Thanks for the comments, I'm still a newbie and this is my first patch.
I have made corrections in accordance with your recommendations.

P.S. Regarding compatible string - since there are no other changes in
the driver, I changed it to "atmel, at91sam9263-ac97c".
But in my opinion, it's a bit ... weird.

AT91SAM9G45 has an AC97 controller, but it is not described in the dts file.
This patch adds AC97 node in device tree.
