Function i2c_master

Attempt to get lock on driver instance.

enum status_code i2c_master_lock(
		struct i2c_master_module *const module)

This function checks the instance's lock, which indicates whether or not it is currently in use, and sets the lock if it was not already set.

The purpose of this is to enable exclusive access to driver instances, so that, e.g., transactions by different services will not interfere with each other.
