iio:common: Removed stuff macros, added num_data_channels on st_sensors struct and added support on one-shot sysfs reads to 3 byte channel
This patch introduce num_data_channels variable on st_sensors struct to manage different type of channels (size or number) in st_sensors_get_buffer_element function. Removed ST_SENSORS_NUMBER_DATA_CHANNELS and ST_SENSORS_BYTE_FOR_CHANNEL and used struct iio_chan_spec const *ch to catch data. Added 3 byte channel data support on one-shot reads.
