broadwell: Add small delay before Flex Ratio reboot
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.
