William Wu 3dfc6a0180 usb: gadget: f_uvc: disallow the CPU to enter deeper sleep when streamon

I test on RK3399 IND EVB running Android R system, and
set the USB gadget as UVC function via configfs, both
the USB 2.0 and 3.0 UVC have preview abnormal problems.
If the CPU enter deeper sleep, the USB DMA transfer gets
corrupted, and the UVC ISOC transmission lost data.

This patch puts in a "pm_qos_latency" requirement which
will keep the CPU out of the deeper sleep states when
UVC stream on. And allow the CPU to enter deeper sleep
state after UVC stream off.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
