[PATCH 5/6] scsi: ufs: exynos: Move phy calls to .exit() callback

[Peter Griffin <peter.griffin@xxxxxxxxxx>]

ufshcd_pltfrm_remove() calls ufshcd_remove(hba) which in turn calls
ufshcd_hba_exit().

By moving the phy_power_off() and phy_exit() calls to the newly created
.exit callback they get called by ufshcd_variant_hba_exit() before
ufshcd_hba_exit() turns off the regulators. This is also similar flow
to the ufs-qcom driver.
