scsi: ufs: qcom: Configure SYS1CLK_1US_REG for UFS V4 and above
SYS1CLK_1US represents the required number of system 1-clock cycles for one
microsecond. UFS Host Controller V4.0 and above mandates to write
SYS1CLK_1US_REG register and also these timer configuration needs to be
called from clk scaling pre ops as per HPG.
Refactor ufs_qcom_cfg_timers and add the below code support to align
with HPG.
a)Configure SYS1CLK_1US_REG for UFS V4 and above.
b)Introduce a new argument is_pre_scale_up for ufs_qcom_cfg_timers
to configure SYS1CLK_1US for max freq during prescale and link startup
condition.
c)Move ufs_qcom_cfg_timers from clk scaling post change ops
to clk scaling pre change ops.
