fips: move FIPS power-up test completion to PMU_PWRDN_SCRATCH22
Status of completion of power-up tests was in long life register
which survives reboots and even firmware upgrades, which is not
an intended behavior. Moving status to PWRDN register makes it
reset on graceful reboots and firmware upgrades, but avoid
running tests on wake from deep sleep. This switch also enables
use of multiple bits to indicate status of tests, which makes it
more fault tolerant.
BUG=b:138577491
TEST=make BOARD=cr50, then deassert DIOM3 to trigger deep sleep
FIPS power-on tests shouldn't run on wake.
