scsi: ufs: qcom : Refactor phy_power_on/off calls

Commit 3f6d1767b1a0 ("phy: ufs-qcom: Refactor all init steps into
phy_poweron") moved the phy_power_on/off from ufs_qcom_setup_clocks
to suspend/resume func.

To have a better power saving, remove the phy_power_on/off calls from
resume/suspend path and put them back to ufs_qcom_setup_clocks, so that
PHY regulators & clks can be turned on/off along with UFS's clocks.

Since phy phy_power_on is separated out from phy calibrate, make
separate calls to phy_power_on calls from ufs qcom driver.
