* Use ACK polling to detect the completion of the write operation.
* Returns TRUE if write is complete (device replies to ACK).
* Note: The device always replies an ACK for the control byte, the polling
* shall be done using the ACK for the memory address byte. Read or write does
* not matter.
* Note: We should sleep a bit between retries, the write time is around 5 ms,
* but the bus is slow, so, a few retries at most will happen.
