Corey Wharton 46ba5e5518 drivers: i2c: i2c_dw: add bus mutex 
This change adds a mutex to protect against simultaneous access to the bus
instead of returning an error during transfers. Since most I2C code doesn't
handle retries (especially with a -EIO code) not blocking on a mutex can
cause a number of problems.
