Subject: scsi: ufs: ufs-qcom: Clear qunipro_g4_sel for HW major version > 5
From: Neil Armstrong <neil.armstrong@xxxxxxxxxx>
commit c422fbd5cb58c9a078172ae1e9750971b738a197 upstream.
The qunipro_g4_sel clear is also needed for new platforms with major
version > 5. Fix the version check to take this into account.
