> Replace device_get_match_data() and i2c_match_id() by i2c_get_match

> v2->v3:
> * Added .name field to MCP4531_ID_TABLE macro
> * Replaced MCP4531_ID_TABLE(name, cfg)->MCP4531_ID_TABLE(_name, cfg)
> v1->v2:
> * Added similar similar I2C and DT-based matching table.
> * Fixed typo i2c_get_match_data(dev)->i2c_get_match_data(client).
> * Dropped error check as all tables have data pointers.
