[PATCH 0/1][SRU][OEM-5.14][J] Lower the volume of expected s0i3 WARN_ON

[Alex Hung]

BugLink: https://bugs.launchpad.net/bugs/1961119

[Impact]

  AMD has a known BIOS bug right now that leads to the WARN
  traceback during s0i3 resume.

  This doesn't have (measurable) functional impact to the system or
  GPU, but it is an ugly message to have in place and makes it look
  like a potentially major problem.

  AMD is working on fixing this in BIOS, but it may not be ready by
  the time the first platforms launch.

[Fix]

  Print a shorter message warning instead:
  "Watermarks table not configured properly by SMU".
  
  The fixed was cherry-picked from mainline kernel v5.17-rc4.

[Test]

  This is requested by AMD, and tested and verified on the AMD CRB.

[Where problems could occur]

  Risk is low. This only changes the behavors of message printing. There are no
  functional changes.
