Subject: [PATCH v1 15/17] iio: chemical: bme680: Remove redundant gas configuration

There is no need to explicitly configure the gas measurement
registers every time a gas measurement takes place. These are
initial configurations which are written in the beginning and
they are not changed throughout the lifetime of the driver.

If in the future, the device starts to support multiple
configuration profiles with variable heater duration and
heater temperature, then they could become members of
the ->read_avail().
