The main difference is that atomisp2 devices do not have a SSDB table with various info. Abstract out the parsing of the sensor's ACPI fwnode into a helper function and store the parsed results, rather then the raw SSDB in struct ipu_sensor. This is a preparation patch for making the ipu-bridge code more generic so that it can be shared with the atomisp driver.
