Add wmi configuration cmd to configure base band(BB) power amplifier(PA) off timing values in hardware. The default PA off timings were fine tuned to make proper DFS radar detection in QCA reference design. If ODM uses different PA in their design, then the same default PA off timing values cannot be used, it requires different settling time to detect radar pulses very sooner and avoid radar detection problems. In that case it provides provision to select proper PA off timing values based on the PA hardware used. The PA component is part of FEM hardware and new device tree entry "ext-fem-name" is used to indentify the FEM hardware. And this wmi configuration cmd is enabled via wmi service flag "WMI_SERVICE_BB_TIMING_CONFIG_SUPPORT". Other way is to apply these values through calibration data, but recalibration of all boards out there might not be feasible. This change tested on firmware ver 10.2.4-1.0-00042 in QCA988X chipset.

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.
