[PATCH 1/3] iio: ABI: add DAC high_z powerdown mode and current output entries

[Kim Seer Paller]

Add high_z powerdown mode for DACs with high impedance output in
current mode (IDAC) and 15kohm_to_gnd resistor to GND. Also add
out_currentY_powerdown_mode, out_currentY_powerdown_mode_available,
and out_currentY_powerdown entries to document current output
powerdown support.
