update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
mantic to verification-done-mantic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-mantic. In either case, without details of your testing we will
not be able to proceed.

Bug description:
  [Impact]
  Some OEM platforms swap DP connections on the Rembrandt-R, which causes 
improper eDP behavior.  The following issues will occur in these designs:

  - Fn key failed to control brightness
  - eDP remains black screen during S0i3 cycle

  AMD has fixed these issues, but it requires both a kernel patch and an
  updated DMCUB microcode.

  [Test Plan]
  Validate brightness control works.
  Validate that PSR works.
  Validate that eDP works after suspend/resume.
  Validate that external display works.

  Run above test plan on Rembrandt or Rembrandt-R system with swapped DP
  as well as one without swapped DP.

  [Where problems can occur]
  The code and DMCUB microcode are localized to AMD Rembrandt/Rembrandt-R 
systems.  Issues would occur specifically on these designs, which is why they 
should be tested.
