    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.
