i2c: i801: replace acpi_lock with I2C bus lock
I2C core ensures in i2c_smbus_xfer() that the I2C bus lock is held when
calling the smbus_xfer callback. That's i801_access() in our case.
I think it's safe in general to assume that the I2C bus lock is held
when the smbus_xfer callback is called.
Therefore I see no need to define an own mutex.
