Channel attribute naming conventions

The attribute's name is automatically generated by the IIO core with the pattern {direction}_{type}_{index}_{modifier}_{info_mask}:

• direction corresponds to the attribute direction, according to the struct iio_direction structure in drivers/iio/industrialio-core.c:

static const char * const iio_direction[] = { 
   [0] = "in", 
   [1] = "out", 
}; 

• type corresponds to the channel type, according to the char array const iio_chan_type_name_spec:

static const char * const iio_chan_type_name_spec[] = { [IIO_VOLTAGE] = "voltage", [IIO_CURRENT] = "current", [IIO_POWER] = "power", [IIO_ACCEL] = "accel", [...] [IIO_UVINDEX] = "uvindex", [IIO_ELECTRICALCONDUCTIVITY] = "electricalconductivity", [IIO_COUNT] = "count", ...
