I checked and the patch is in the package.  I also tried this on cosmic and bionic and worked fine.  From cosmic:
ubuntu at ltc-boston25:~$ dpkg --list |grep opal-prd

ubuntu at ltc-boston25:~$ sudo opal-prd occ reset 08h
ubuntu at ltc-boston25:~$ cat /etc/*release* |grep VER

Bug description:
  [Impact]

  - Without the fix, the system will crash on upstream hostboot with NMI enabled systems when opal-prd occ reset is triggered on OpenBMC boxes
  - This patch enables HBRT to use HYP special wakeup register in openBMC which until now was only used in FSP based machines

  [Testcase]

  - opal-prd occ reset

  [Regression Potential]
  - Failure of OCC reset command

  [Other Info]

  On upstream hostboot with NMI enabled, opal-prd occ reset crashes. The following upstream patch needs to be backported to the package to avoid the error.

  commit 05dc67bf4f3d85fc6212d1644d46ce6d8bd71140
  opal-prd: hservice: Enable hservice->wakeup() in BMC
