iio: dac: mcp4725: Add basic support for MCP4726
MCP4726 is a single channel 12-bit DAC. We can support MCP4726 with
a little changes to mcp4725 driver. In power-down mode, they have
different selection of VOUT pull-down registers.
MCP4726 also has features:
- Output gain options: 1x, 2x
- Voltage reference selection: VDD, VREF (Unbuffered or Buffered)
But these are not supported in this change. (1x gain, VDD is selected)
