[PATCH V6 4/6] scsi: ufs: qcom: Align unipro clk attributes configuration as per HPG

From: Nitin Rawat
Date: Fri Sep 01 2023 - 07:45:02 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 completely with hardware
specification. This doesn't bring any functionality change.
