iio: adc: mcp3422: Add support for MCP3425
The MCP3425 is a single channel up to 16-bit A/D converter which has
features:
- On-Board Programmable Gain Amplifier (PGA):
- Gains of 1, 2, 4 or 8
- Programmable Data Rate Options:
- 15 SPS (16 bits), 60 SPS (14 bits), 240 SPS (12 bits)
The mcp3422 driver also supports the MCP3421 which is a single channel.
So we can support MCP3425 with a little changes to mcp3422 driver.
