intel/fsp1_1: Do not re-init TPM in romstage if already setup in verstage
For platforms that do verification of memory init (and have verstage
execute before romstage) FSP should not attempt to re-initialize the
TPM again in romstage as it has already been done.
BUG=chrome-os-partner:50633
BRANCH=glados
TEST=boot and resume on chell and ensure TPM is not re-initialized
