vboot: Handle S3 resume path for TPM initialization
When doing verification of memory init code in verstage vboot
should issue a TPM_Startup(ST_STATE) instead of TPM_Startup(ST_CLEAR)
in order to preserve the flags in TPM_STCLEAR_FLAGS which include
things like physical presence. In doing so we can also skip the rest
of the TPM init work in this function in the S3 resume path.
BUG=chrome-os-partner:50633
BRANCH=glados
TEST=S3 resume on chell and ensure TPM is resumed instead of being
cleared and that 'tpmc getvf|getpf|getf' does not show any difference
in flags between boot and resume.
