Aseda Aboagye d7303404a5 cr50: Make sure TPM wipe only clears TPM data. ...

Previously, wiping the TPM would wipe all of NvMem, however, it really
should only clear the TPM's NvMem space.  This commit adds a function to
clear a given NvMem user's space and makes the TPM only clear its space.

BUG=chrome-os-partner:61597
BRANCH=None
TEST=Add code for using nvmem vars, create a test variable, add a user
to snappy, unlock the console, verify that the user is no longer present
on the system and the test nvmem var still exists.
TEST=make -j buildall
