Subject: [PATCH 1/3] hwmon: scmi: Add default case with debug output

From: Artem Shimko <artyom.shimko@...il.com>

Improve handling of unsupported sensor types:
- Add default case in sensor type switch statement
- Log skipped sensors with debug information including:
  * Sensor ID
  * Sensor type
  * Sensor name (if available)
- Use rate-limited dev_dbg for safety

Debug output format:
"Skipping unsupported sensor ID:%d Type:%d (%s)"
