storm: reset TPM properly on proto0
The proto0 storm hardware has the TPM reset line wired to the SOC GPIO22
pin instead of the system reset. This causes all kind of TPM behavior
problems and requires frequent power cycles. Adding explicit TPM reset
makes all those problems go away.
BUG=chrome-os-partner:30705, chrome-os-partner:30829
TEST=tried resetting proto0 at different moments during boot up - the
TPM does not fail anymore.
