[PATCH] i2c: Remove setting for 1 second timeout from adapter drivers

[PATCH] i2c: Remove setting for 1 second timeout from adapter drivers

[Jarkko Nikula]

I2C adapter drivers that are using 1 second timeout can leave the timeout
unset and let the i2c-core.c: i2c_register_adapter() to set it instead.
