1. Added a flag to issue START command
2. Do not send START command inside i2c_start function as
   the LPI2C hardware will issue a STOP on reception
   of a NACK
3. Remove the i2c_address global variable, this is not
   required

1. Remove the repeated_start flag and code as this is not needed
   for the LPI2C module
2. Enable the SION bit on the I2C pins
3. Enable 22K Pullup option of the I2C pins
4. Update the 0 byte write implementation to ensure the START
   command gets flushed out of the FIFO
