[Ritesh Kumar]

Commit 77d2fa54a9457 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls") lead to edp reference clock to be turned off, leading to
below phy poweron failure on lemans edp phy.

phy phy-aec2a00.phy.10: phy poweron failed --> -110

edp reference clock is required to be enabled before edp PHY
initialization. This change adds support for voting the clock
from edp phy driver.
