BREAKING CHANGE: bme680_register() takes an additional "*config" argument. When config is NULL - driver behavior is the same as before. With this change bme680 can be configured during registration in board logic. This way we don't have to callibrate sensor from user-space but sensor is ready to use after registration. This change makes the registration the same as for bme688, which is a similar sensor. Signed-off-by: raiden00pl <raiden00@railab.me>
