Simon Glass 182bf92d19 dm: i2c: Add an explicit test mode to the sandbox I2C driver
At present this driver has a few test features. They are needed for running
the driver model unit tests but are confusing and unnecessary if using
sandbox at the command line. Add a flag to enable the test mode, and don't
enable it by default.
