[PATCH v6 3/3] scsi: ufs: Revert "Make sure clk scaling happens only when HBA is runtime ACTIVE"

[Can Guo]

Commit 73cc291c27024 ("Make sure clk scaling happens only when HBA is
runtime ACTIVE") is no longer needed since commit f7a42540928a8 ("scsi:
ufs: Protect some contexts from unexpected clock scaling") is a more
mature fix to protect UFS LLD stability from clock scaling invoked through
sysfs nodes by users.
