iio: dac: mcp4821: add configurable gain support
Add support for configuring the DAC gain using the GA bit
The MCP4821 supports two gain settings:
- 1x gain → 2.048V full-scale
- 2x gain → 4.096V full-scale
Scale write support is added in the IIO interface. Only scale
values advertised via the scale_available attribute are accepted,
ensuring consistency between the configured gain and exposed
scale values.
