scsi: ufs: host: mediatek: Add debug information for Auto-Hibern8
Enhance the clock gating logic by adding debug information for the
Auto-Hibern8 (AHIT) register. This additional logging aids in
troubleshooting by providing insights into the AHIT configuration when
the clock is not turned off as expected.
