Add device tree binding for the LTC2305, a 2-channel, 12-bit SAR ADC
from Linear Technology (now part of Analog Devices).
The LTC2305 uses the same I2C register interface as the LTC2309 but
differs in:
- Channel count: 2 channels vs 8 channels (LTC2309)
- Conversion timing: Requires 1.6μs settling time vs negligible for
LTC2309
