i2c-imx: fix low bitrate problem ...

loop in i2c_imx_acked() in low bit rates it takes some time until the
ACK comes in.

Also add a delay before polling for bus not busy in i2c_imx_read.

i2c-imx: fix clear IFF race condition ...

During i2c read the original pattern was:

1. write i2c slave address
2. wait for transmit complete + clear IIF
3. wait for receive acknowledge
4. wait for IIF interrupt

Due to the clear of the I2SR register, the IIF flag was cleared, too. So
in step 4 the Interrupt wasn't detected. To fix this problem, we move
the clean of IIF before the writing of the slave address. So that it
looks this way:

0. clear IIF
1. write i2c slave address
2. wait for transmit complete
3. wait for receive acknowledge
4. wait for IIF interrupt
