[PATCH] iio: pressure: bmp280: Fix incorrect pointer access in PM callbacks

[Jarkko Nikula <jarkko.nikula@linux.intel.com>]

BMP280 runtime PM callbacks are incorrectly casting dev_get_drvdata() to
struct bmp280_data * while bmp280_common_probe() sets driver data to
struct iio_dev *. Fix this and get the struct bmp280_data * from private
data of struct iio_dev.

Fixes: 3d838118c6aa ("iio: pressure: bmp280: add power management")
