[PATCH] iio: st_common: use standard trigger suffix

[Linus Walleij <linus.walleij@linaro.org>]

The triggers from ST sensors are named <iio_device_name>-trigger
instead of the standard <iio_device_name>-dev<iio_dev_id> as
used by most and also in the iio-tools. Change this to match
the norm.

After this I can do tests with generic_buffer -n <dev_name>
without having to manually specify the trigger with the -t
option.
