Alan Ott 0afbb0e1c0 i2c: at91_i2c: Wait for TXRDY after sending the first byte
The driver must wait for TXRDY after each byte is pushed into
the i2c FIFO before pushing the next byte. Previously this was
not done for the first byte, causing a race condition with zeros
sometimes being sent for the next byte (which is typically the
first actual data byte).
