This should be landed to Noble and OEM-6.8 automatically when stable fixes are rebased, however we may need it before that.

========== original bug report ==========

AMD VPE (Video Processing Engine) behavior breaks s2idle for AMD Strix platform, so adding VPE power-up to ensure FW loading properly. The patch landed in v6.8.7, oem-6.8 will have it once rebased.
