In order to prevent possible TPM lockout due to PLTRST assertion shortly after powering up add a small delay before the reset. This will affect cold power up only, reboot/resume/warmboot will all have the flex ratio locked already so this reset is unneeded. BUG=chrome-os-partner:29859 BRANCH=None TEST=build and boot on samus. I tried unsuccessfully to trigger the TPM lockout, but I was not able to do that consistently without this patch so it is unknown yet whether this is 100% effective.
