Move platform independent stub calls back to

Browse Source 
the third_party tpm library.

Some files in the third_party TPM2 source are
omitted from compilation (e.g. CpriHash.c) as they
contain platform dependent code.  Subsequently all
the functions necessary for compilation were moved
to stubs.c.  However, some of these functions are
platform independent, and should remain in the
third_party implementation.

The corresponding change CL:321375 adds such functions
to third_party/tpm.

TEST=compilation succeeds
