iio: dac: mcp4725: Add dac_reg_offset to struct mcp4725_chip_info

The MCP4725 has a register offset '3' for reading DAC value compared to
'4' for MCP4726. Add dac_reg_offset variable to struct mcp4725_chip_info
to handle this difference.

Drop chip_id from struct mcp4725_chip_info as it is unused.
