Custom sensor attributes for MCP9600.

Enumerator
SENSOR_ATTR_MCP9600_ADC_RES	ADC resolution. sensor_value.val1 is the resolution value (see mcp9600_adc_resolution). sensor_value.val2 is unused (always 0).
SENSOR_ATTR_MCP9600_FILTER_COEFFICIENT	IIR filter coefficient (0-7). sensor_value.val1 is the filter coefficient. sensor_value.val2 is unused (always 0).
SENSOR_ATTR_MCP9600_THERMOCOUPLE_TYPE	Thermocouple type. sensor_value.val1 is the thermocouple type (see mcp9600_thermocouple_type). sensor_value.val2 is unused (always 0).
SENSOR_ATTR_MCP9600_COLD_JUNCTION_RESOLUTION	Cold junction temperature resolution. sensor_value.val1 is the resolution value (see mcp9600_cold_junction_resolution). sensor_value.val2 is unused (always 0).
SENSOR_ATTR_MCP9600_DEV_ID	Device ID (read-only). sensor_value.val1 is the 16-bit device ID (chip ID in high byte, revision in low byte). sensor_value.val2 is unused (always 0).

sensor_channel_mcp9600

enum sensor_channel_mcp9600

#include </__w/bridle/bridle/workspace/zephyr/include/zephyr/drivers/sensor/mcp9600.h>

Enumerator
SENSOR_CHAN_MCP9600_COLD_JUNCTION_TEMP	Cold junction (reference) temperature in degrees Celsius. sensor_value.val1 is the integer part of the temperature (°C). sensor_value.val2 is the fractional part (in millionths of a degree).
SENSOR_CHAN_MCP9600_HOT_JUNCTION_TEMP	Hot junction (thermocouple tip) temperature in degrees Celsius. sensor_value.val1 is the integer part of the temperature (°C). sensor_value.val2 is the fractional part (in millionths of a degree).
SENSOR_CHAN_MCP9600_DELTA_TEMP	Temperature difference (hot junction minus cold junction) in degrees Celsius. sensor_value.val1 is the integer part of the delta temperature (°C). sensor_value.val2 is the fractional part (in millionths of a degree).
SENSOR_CHAN_MCP9600_RAW_ADC	Raw ADC value (thermocouple EMF in ADC counts). sensor_value.val1 is the raw 24-bit signed ADC value. sensor_value.val2 is unused (always 0).
