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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
