Jay Vasanth 3034693509 drivers: i2c: MEC15xx: Improved error handling 
1. Check I2C Clock and Data is high through GPIO driver instead
of the I2C bitbang registers
2. i2c_xec_poll_write() and i2c_xec_poll_read() will poll to
check I2C clock and data lines are high before initiating the
transaction. The polling will be every 25us for a cumulative
max of 2.5ms
3. wait_completion() will not call recover_from_error() to reset
the controller. Instead will poll for 10ms for the PIN bit to
clear before returning error.
4. wait_completion() will send STOP if the 9th bit is NACK
5. If any errors with current transaction:
(a) Set error_seen flag.
(b) In the next transaction do the recovery process (reset the
i2c controller) if the clk and data lines are high.
Note: error_seen flag is set for Address NACK with Repeated
Start as well.
6. If timeout error occurs in wait_completion():
(a) Set timeout_seen flag;
(b) Wait till the slave will release the clock.
(c) Once slave releases clock send STOP on the bus. If the
timeout occurred while master read, read the I2C DATA register
for the hardware to proceed.
