[PATCH 1/2] iio: adc: ad7380: make ad7380_regmap_config static

[David Lechner <dlechner@baylibre.com>]

ad7380_regmap_config is not used outside of ad7380.c, so make it static.

Fixes sparse warning:

     drivers/iio/adc/ad7380.c:205:28: sparse: sparse: symbol
     'ad7380_regmap_config' was not declared. Should it be static?
