The st_sensors_core driver hardcodes the content of the
iio_device_claim_direct_mode() and iio_device_release_direct_mode()
helpers. Let's get rid of this handcrafted implementation and use the
proper core helpers instead. Additionally, this lowers the tab level
(which is always good) and prevents the use of the ->currentmode
variable which is not supposed to be used like this anyway.
