tpm_nvmem_ops.c: add function to get size of nvmem hidden objectstabilize-quickfix-13310.91.B-cr50_stabstabilize-quickfix-13310.76.B-cr50_stabstabilize-quickfix-13310.73.B-cr50_stabstabilize-13310.99.B-cr50_stabstabilize-13310.94.B-cr50_stabstabilize-13310.83.B-cr50_stabstabilize-13310.74.B-cr50_stabstabilize-13310.72.B-cr50_stabrelease-R85-13310.B-cr50_stab
Added service function read_tpm_nvmem_size() to return size of hidden
nvmem object, which is needed in FIPS framework code, but can't be
implemented locally due to conflicting headers between TPM2 library
and Cryptoc library, and util.h
BUG=none
TEST=make BOARD=cr50; meaningul test will be added in upcoming CLs
