c4e58eaa98 stmhal/i2c: Add option to I2C to enable/disable use of DMA transfers. 
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).
