[PATCH v5 4/6] drivers/i2c: Add I2C master locking to FSI algorithm

From: "Edward A. James" Since there are many ports per master, each with it's own adapter and chardev, we need some locking to prevent transfers from changing the\ master state while other transfers are in progress. Signed-off-by: Edward A. James ---
