New keyword option in constructor and init() method is "dma=<bool>".
DMA is now disabled by default for I2C transfers because it currently does
not handle I2C bus errors very well (eg if slave device doesn't ACK or
NACK correctly during a transfer).
tests: For pyboard, add test for I2C error handling and recovery.2016-01-30T00:06:04+00:00Damien Georgedamien.p.george@gmail.com2016-01-30T00:06:04+00:00urn:sha1:ef5f2669dcff068a0b7ed9cdb94acecc060440f6
