Update JSON/events for power10 platform with additional events. Also move PM_VECTOR_LD_CMPL event from others.json to frontend.json file.

Hi Arnaldo, Thanks for fixing it. I will make sure in next series of patches, we are also checking for this combination to avoid ascii issue. Change looks fine to me. Thanks, Kajol Jain
