Currently UFS clk scaling is getting suspended only when the clks are scaled down. When high load is generated, a huge amount of latency is added due to scaling up the clk and completing the request post that. Suspending the scaling in its existing state when high load is generated improves the random performance KPI by 28%. So suspending the scaling when there are no requests. And the clk would be put in low scaled state when the actual request load is low. Make this change optional by having the check enabled using vops since for some devices suspending without bringing the clk in low scaled state might have impact on power consumption of the SoC.

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 reStructuredText 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.
