I2C doc rx commands fix

[Bart Veer]

Sorry for the delay in getting this checked in. While testing the
changes I ran into a strange problem which turned out to be not
directly related to the i2c code, but took a while to track down.

Applied. There was also a missing send_nack argument to the device
driver rx function so that is now fixed as well.

Applied. As discussed I have also added a CYG_HAL_TABLE_TYPE to the
bus data structure.

Applied.

Thanks for these fixes.
