Add dt-bindings and driver support for AD5110, a Nonvolatile
Digital Potentiometer.

Changes since v2:
- Drop Redundant blank lines
- Add missed prefix name
- Add comma to non terminator line
- Add missed error code return when ret < 0
- Explanation for msleep(20)
- Change to IIO_DEVICE_ATTR_RW()
- Remove comma for terminator line
- Drop data->cfg dead code since I'm using probe_new()

Changes since v1:
- Drop 'shared_by_type' since it's a single channel
- Add error check for i2c read/write data bytes
- Simplified calculation for tolerance
- Add shift for eeprom wiper pos read
- Change new custom ABI to existing ABI
- Allow top-scale mode by writting max_pos to val
