Dennis Li 26eb6b51da drm/amdgpu: fix a GPU hang issue when remove device
When GFXOFF is enabled and GPU is idle, driver will fail to access some
registers. Therefore change to disable power gating before all access
registers with MMIO.

Dmesg log is as following:
amdgpu 0000:03:00.0: amdgpu: amdgpu: finishing device.
amdgpu: cp queue pipe 4 queue 0 preemption failed
amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2
amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706
amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2
amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706

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.

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.
