Add a new iio_fixup_sampling_frequency() helper to iio-buffer-utils.c and call this for all iio devices. iio_fixup_sampling_frequency() makes sure that devices with *sampling_frequency attributes are sampling at 10Hz or more. This fixes 2 problems: 1) Some buffered devices default their sampling_frequency to 0Hz and then never produce any readings. This fixes e.g. the sensors on Asus T100HA 2-in-1s not working. 2) Some polled devices default to 1Hz and wait for a fresh sample before returning from sysfs *_raw reads, blocking all of iio-sensor-proxy for multiple seconds, this fixes e.g. rotation being detected up to 10 seconds later then the actual rotating of the device on a Lenovo Miix 320.
