The CSE expects the boot firmware to send it an End-of-Post message
before loading the OS. This is a security feature, and is done to ensure
that the CSE will no longer perform certain sensitive commands that are
not intended to be exposed to the OS.
If processing the EOP message fails in any way on a ChromeOS build, (and
not already in recovery mode), recovery mode will be triggered,
otherwise the CSME BWG will be followed, which is in the following
commit.

One of the reason FSP-T support had to be kept in place was for
Intel Bootguard. This now works with native CAR code, so there is no
reason to keep FSP-T as an option for these platforms.
APL did not even build with FSP_CAR and finding FSP-T using walkcbfs
was only recently fixed using FMAP, so there can be no doubt that this
option was never used with coreboot master.

pmc_set_power_failure_state() is usually called twice, once upon boot
(with `target_on == true`) and once from SMM when the system is shut
down (with `target_on == false`). Assuming settings didn't change
between these calls, there is only one case where we actually need
to write the register value: when updating the state for the
MAINBOARD_POWER_STATE_PREVIOUS feature.
This suits us well as we want to avoid unnecessary writes so we
don't clobber the value set upon boot from within SMM. Due to
inaccessible option backends, SMM might not know the current
option state.
The assumption above, that the option value didn't change, may not
be true if the user changed the option on purpose. In the future,
one would have to reboot the machine for option changes to take
effect. However, this doesn't seem to make a huge difference: One
already needed a controlled shutdown for the update to take effect
before. A reboot doesn't seem much more expensive.

This patch create separate helper functions to fill-in required
FSP-M UPDs as per IP initialization categories.
This would help to increase the code readability and in future
meaningful addition of FSP-M UPDs is possible rather adding UPDs randomly.
TEST=FSP-M UPD dump shows no change without and with this code change.
