Subject: [PATCH V6 01/10] scsi: ufs: qcom: Prevent calling phy_exit before phy_init

Prevent calling phy_exit before phy_init to avoid abnormal power
count and the following warning during boot up.

[5.146763] phy phy-1d80000.phy.0: phy_power_on was called before phy_init

Fixes: 7bac65687510 ("scsi: ufs: qcom: Power off the PHY if it was already powered on in ufs_qcom_power_up_sequence()")
