Randall Spangler b94747d501 cr50: reset only the TPM state on SYS_RST_L

Rather than doing a full cr50 reset when the system reset SYS_RST_L is
asserted, just reset the state of the TPM task and library.  Re-clear
.bss for those modules, then re-initialize.

BRANCH=none
BUG=chrome-os-partner:52366
CQ-DEPEND=CL:366792
TEST=make buildall; test on Gru

Trigger a SYS_RST_L by using the AP's reboot command, power
off/on, log in/out/in.

See that the Cr50 does not reboot and the firmware and userspace
are still happy about the TPM.
