iio: hx711: add triggered buffer support
Add buffer to device data struct and add trigger function
Data format is quite simple:
voltage - channel 0 32 Bit
voltage - channel 1 32 Bit
timestamp 64 Bit
Using both channels at the same time is working quite slow because of
changing the channel which needs a dummy read.
