The fallback certificate is provided when TPM is starting up, but the
proper endorsement certificate seed is not found in the RO space.
Unavailability of the proper endorsement cert would be a major failure
for the device using TPM, and it is not supposed to happen: RO space
is protected. On top of that there is no much point in operating with
the fallback certificate.
Let's drop fallback certificate support from the code, leaving it
possible to conditionally compile in for the remote chance of someone

This adds some of the ground work for hardware backed brute force
resistance on Cr50. The feature is called Pinweaver. It will
initially be used to enable PIN authentication on CrOS devices
without reducing the security of the platform. A Merkle tree is
used to validate encrypted metadata used to track login attempts.
The metadata tracks counts of failed attempts, a timestamp of the
last failed attempt, the secrets, and any associated parameters.
Instead of storing the metadata on Cr50 an AES-CTR is used with an
HMAC to encrypt the data so it can be stored off-chip and loaded
when needed.
The Merkle tree is used to track the current state of all the
metadata to prevent replay attacks of previously exported copies.
It is a tree of hashes whose root hash is stored on Cr50, and whose
leaves are the HMACs of the encrypted metadata.

Currently, if a board supports dual role power ports, the EC will
briefly apply Rp resistors on the CC lines upon initializing the PD
tasks. This was put in place such that the partner port is a known
state. In the case of an external PD charger, the presence of the Rp
will cause the charger to stop sourcing VBUS. We only apply the pull up
for reset cases where the EC did not just loose power (e.g. power on
reset or brownout).
This however presents a problem when booting off of AC only. If a user
types 'reboot ap-off', there will be an extra reset because VBUS is
dropped and the "ap-off" flag will be lost.
This commit simply checks to see if there is an explicit contract in
place for a port. If an explicit contract is in place and PD
communications are allowed, we will not apply the Rp resistors. The PD
state machine will then attempt to send a SoftReset to the port partner
in order to reset the PD protocol layer. If an explicit contract is not
in place, or if PD communications are not allowed, the Rp's will be
asserted briefly as before.

Apparently the symbol in the yorp schematic is incorrect for our part.
The PMIC_EN signal on ball H6 is actually GPIO72 -- not GPIOD7. Adjust
the gpio used for PMIC_EN.
Note: GPIO72 needs to be put in gpio mode since it defaults to PWRGD
functionality. However, gpio_pre_init() in chip/npcx/gpio.c enables
gpio functionality by default. If that changes, the board options will
need to change as well.
BUG=b:78352179
TEST=Built. Booted. PMIC_EN goes up and down as expected.
BRANCH=none
