security/vboot: ensure that NVMEM is saved on every kernel space write
If the AP actually needs to write to the TPM, then it is important and
the TPM should commit those changes to NVMEM immediately in case there
is an unexpected power loss (e.g. from a USB-C port partner reset upon
cold reboot request).
BRANCH=none
BUG=b:160913048
TEST=Verify that puff will no longer reboot loop when coreboot writes a
new Hmir (Hash mirror) in the TPM
