Bernardo Perez Priego 42fcca480b drivers: i2c: microchip: Add mutex to transaction implementation 
Currently, I2C transfer implementation does not have a mutex to
prevent multiple users from sending data at the same time, this could
lead to devices malfunction due to mixing I2C transaction data.

This patch adds mutex into transfer implementation to allow only one
user to send data at the time.
