Well, here I would like "atmel,sama5d2-i2c" like any other "SAMA5" product compatibility string out there...

add a new value "atmel,at91sama5d2-i2c" for the "compatible" property. add a new optional property "atmel,fifo-size" to enable FIFO support when available. add missing optional properties "dmas" and "dma-names".
