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.

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.
