Add method for delaying adding of timestamps

In hardwaremain() we can't add timestamps before we actually
reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged
in hardwaremain() when coming out of an S3 resume.

The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c
