[PATCH v1 03/10] ufs: host: mediatek: Add debug information for Auto-Hibern8

[peter.wang at mediatek.com]

From: Peter Wang <peter.wang at mediatek.com>

This patch enhances 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.
