If the timestamp entries are added out of order, the duration
calculation will be wrong.
AGESA collects timestamp data through all the stages. Then in AmdInitPost
it asks for a buffer to write TP_Perf_STRUCT into. agesawrapper will then
take the data and call timestamp_add on each entry. This results in
the entries being out of order.
TEST=Built firmware for grunt that manually added entries and then ran
cbmem -t/-T to verify the entries were in the correct order.
