  4. [dev_asynch_i2c] HAL Fix to support Master Rx w/ repeated start 

    As per reference manual, closing communication for master receiver
with repeated start requires, after reading second last data byte
(after second last RxNE event):
-Clearing ACK bit (same as non repeated start case)
-Set START bit (instead of STOP bit in non repeated start case)
This is valid for I2C_FIRST_FRAME and I2C_NEXT_FRAME conditions

  5. [dev_i2c] Fix I2C byte transfer API to enable Master/Slave test on F4… 

    …11RE

i2c_byte_write could be used to send byte and address.
In case used for address, ADDR Flag should be reset.
