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.

Add device tree bindings for the Analog Devices AD5710R/AD5711R 8-channel 12-/16-bit Configurable IDAC/VDAC. Signed-off-by: Kim Seer Paller <kimseer.paller@analog.com>
The AD5710R (16-bit) and AD5711R (12-bit) are 8-channel, low-power, configurable current/voltage output DACs with an on-chip 2.5V, 3ppm/°C reference. Each channel can be independently configured as a voltage output (0V to VREF or 0V to 2xVREF) or a current output (0mA to 50mA). These devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. Signed-off-by: Kim Seer Paller <kimseer.paller@analog.com>

PR Description
This PR adds support for the AD5710R (16-bit) and AD5711R (12-bit) 8-channel configurable IDAC/VDAC.
Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ad5711r-ad5710r.pdf
The AD5710R/AD5711R shares a similar register interface with the
AD3530R family but introduces current output (IDAC) support alongside
voltage output (VDAC), independently configurable per channel. This
brings additional complexity in channel mode configuration and
powerdown handling (high_z for IMODE, 15kohm_to_gnd for VMODE).
Rather than extending the AD3530R driver - which is already growing
in complexity with AD3532R dual-bank support (#3177) - this is
introduced as a dedicated driver.
Looking for feedback on whether keeping this as a separate driver is
the right approach, or if it should be folded into the AD3530R driver.
