Ye Li d144f61ad3 lpi2c: Fix bus stop problem in xfer 
In xfer function, both bus_i2c_read and bus_i2c_write will
send a STOP command.  This causes a problem when reading register
data from i2c device.

Generally two operations comprise the register data reading:
   1. Write the register address to i2c device.
      START | chip_addr | W | ACK | register_addr | ACK |

   2. Read the Data from i2c device.
      START | chip_addr | R | ACK | DATA          | NACK | STOP

The STOP command should happen at the end of the transfer, otherwise
we will always get data from register address 0
