iio: adc: hx711: optimize performance in read cycle
Set gain in hx711_reset() to its default value after a reset cycle. This
omits one precautionary read cycle, because the read is performed in
hx711_set_gain_for_channel() anyway if gain has changed.
Check for DOUT low and if its high wait some time if it goes down
instead of doing a blind reset cycle when DOUT is not down.
This is a performance optimization which allows to query the sensor with
a higher frequency.
