Alvin Lee 6ba5a269cd drm/amd/display: Update vactive margin and max vblank for fpo + vactive
[Description]
- Some 1920x1080@60hz displays have VBLANK time > 600us which we
  still want to accept for FPO + Vactive configs based on testing
	- Increase max VBLANK time to 1000us to allow these configs
	  for FPO + Vactive
- Increase minimum vactive switch margin for FPO + Vactive to 200us
	- Based on testing, 1920x1080@120hz can have a switch margin
	  of ~160us which requires significantly longer FPO stretch
	  margin (5ms) which we don't want to accept for now
- Also move margins into debug option

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.
