hwmon: (scmi) handle absence of few types of sensors
Currently the loop checks for non-zero count of sensors for each type of sensors which is completely wrong. It also results in aborting the registration of sensors if one or more types of sensors are completely not supported by the platform SCMI firmware. This patch fixes the issue by continue to loop and skiping sensor types that are not present.
