Hi,

AT91RM9200 is gaining DT support now so let's add an id to the i2c driver.

Tested on custom RM9200 board. Since the driver doesn't support pinctrl
muxing yet I had to add pinctrl hogs for the i2c pins in my dts for it
to work.

IIRC the i2c IP have quite a lots of issue on rm9200 and until sam9g45

it not recommended to use it instead use i2c-gpio

Ludovic, you know the driver best. Does it make sense to add this?

Best Regards,
J.
