iio: potentiometer: tpl0102: switch to using pointer to chip config
More concise to have a pointer to tpl0102_cfg struct in the iio_priv data than an integer to an index of an array. Signed-off-by: Matt Ranostay <matt.ranostay@konsulko.com> Reviewed-by: Slawomir Stepien <sst@poczta.fm> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
