Brennan Ashton bbf16b27d9 nRF52: Add basic error handling for i2c in polling mode
There was no error handling before and it would block on common
cases like NACK which meant that you could not use the i2ctool
to perform a scan of the bus.

This does not handle the interrupt flow which also has incomplete
error handling.
