scsi: ufs: qcom: Add support to configure PA_VS_CORE_CLK_40NS_CYCLES
PA_VS_CORE_CLK_40NS_CYCLES attribute represents the required number of
Qunipro core clock for 40 nanoseconds. For UFS host controller V4 and above
PA_VS_CORE_CLK_40NS_CYCLES needs to be programmed as per frequency of
unipro core clk of UFS host controller.
Add Support to configure PA_VS_CORE_CLK_40NS_CYCLES for Controller V4 and
above to align with the hardware specification and to avoid functionality
issues like h8 enter/exit failure, command timeout.
