[PATCH V5 4/6] scsi: ufs: qcom: Align unipro clk attributes as per Hardware specification

From: Nitin Rawat
Date: Wed Aug 23 2023 - 11:44:38 EST


Currently CORE_CLK_1US_CYCLES, PA_VS_CORE_CLK_40NS_CYCLES are configured
in clk scaling post change ops. Move this to clk scaling pre change ops to
align with the hardware specification.
