Prike.Liang b6df946ef4 drm/amdgpu: fix the nullptr issue as for PWR IP not existing in discovery table 
Fixes: c1cf79ca5c ("drm/amdgpu: use IP discovery table for renoir")

This nullptr issue should be specific on the Renoir series during try access the PWR_MISC_CNTL_STATUS
when PWR IP not been detected by discovery table. Moreover the PWR IP not existing in Renoir series is
expected therefore just avoid access PWR register in Renoir series.

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.
