tpmtest: Make it work with current cr50
A couple of changes are needed to make tpmtests run with the
latest cr50:
1. The CRYPTO_TESTS flag turns off the TPM in cr50 build, so
no need to initalize TPM.
2. FW_UPGRADE protocol now uses offset into flash instead of
absolute memory addresses to perform upgrade.
BUG=None
TEST=test/tpm_test/tpmtest.py runs and all tests pass
