[PATCH 6/7] phy: qcom-ufs-qmp-xx: Move clock and regulator init out of phy init

From: Vivek Gautam
Date: Tue Oct 18 2016 - 00:50:25 EST


The phy init is meant to do phy initialization rather than
just getting the clock and regulator. Move these clock and
regulator get to probe(), to make room for actual phy
initialization sequence.
