i2c: at91: add dma support Add dma support for Atmel TWI which is available on sam9x5 and later. When using dma for reception, you have to read only n-2 bytes. The last two bytes are read manually. Don't doing this should cause to send the STOP command too late and then to get extra data in the receive register.
