The bootstate machine allows one to schedule work at the
boundaries of each state. However, there are no priorities by
design. As such if there are things that need to be performed
that are interdependent between callbacks there's no way to
do that aside from explicitly putting the call in one of the
callbacks.
This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD,
and BS_PAYLOAD_BOOT as those are the states where coreboot is
about to exit. As such, provide an architecture specific hook
at these key places so that one is guaranteed any work done
in arch_bootstate_coreboot_exit() is after all callbacks in
the state machine.

The MRC cache uses an incoherent mechanism for updating the
cache contents in that it assumes memory mapped boot device
access for checking against latest data for update. However,
it uses another driver for updating the underlying storage
area.
In order to aid in moving the MRC cache over to using
region_devices for updates provide an implementation of
a region_device which performs reads and writes to different
region_devices so that different drivers can be used
transparently.

this doesn't matter because the elog library only uses 4KiB bytes.

- Moved RW_NVRAM for subsequent alignment.
- Most importantly, RW_SECTION_(A|B) are aligned to 64KiB boundaries

Gru only uses USB 2.0 in firmware to avoid all the madness associated
with Type-C port orientation and USB 3.0 tuning. We do this by isolating
the SuperSpeed lines in the Type-C PHY so it looks like they aren't
connected to the device.
Unfortunately, some devices seem to already get "locked" into SuperSpeed
mode as soon as they detect Rx terminations once, and can never snap out
again on their own. Since the terminations are already connected during
power-on reset we cannot disable them fast enough to prevent this, and
the only solution we found to date is to power-cycle the whole USB port.
Now, Gru's USB port power is controlled by the EC, and unfortunately we
have no direct host command to control it. We do however have a command
to force a certain USB PD "role", and forcing our host into "sink" mode
makes it stop sourcing power to the port. So for lack of a saner
solution we'll use this to work around our problem.
