For x86 systems which resume through the reset vector one needs to
ensure the the RW slot taken at resume time matches the one at
boot time. To that end, allow Chrome OS EC to supply the plumbing
to vboot for storing and retrieving the RW slots' hash digest
using the vstore backend.

On certain Winbond SuperIO devices, when a PS/2 mouse is not
present on the auxiliary channel both channels will cease to
function if the auxiliary channel is probed while the primary
channel is active. Therefore, knowledge of mouse presence
must be gathered by coreboot during early boot, and used to
enable or disable the auxiliary PS/2 port before control is
passed to the operating system.
Add auxiliary channel PS/2 device presence detect, and update
the Winbond W83667HG-A driver to flag the auxiliary channel as
disabled if no device was detected.

This adds basic ACPI support for the EC used on Purism Librem laptops.
The EC firmware appears to use the topstar laptop interface that has
support in the linux kernel for handling the special keys.
Supported functions:
- Battery information
- AC presence
- Lid switch
- Special keys (after loading topstar-laptop driver in linux)
- EC events for turbo enable/disable when on AC power
Things it does not do:
- EC SMI handling
- Fan is left under EC control
This was developed and tested on a Librem 13 laptop, and has not
been directly tested on an Librem 15.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

This patch adds a few retries to NVRAM read/write transactions with the
EC. Failing to read the NVRAM is not fatal to the boot, but it's still
pretty bad... especially since a single initial read failure will cause
vboot to blindly reinitialize the whole NVRAM with zeroes, destroying
important configuration bits like dev_boot_usb. The current EC
transaction timeout is one second, so the three retries added here can
potentially increase boot time by three seconds per transaction... but
this shouldn't happen in any normal case anyway, and if there are errors
a little extra wait is probably preferrable to nuking your NVRAM.
(Also, added a missing newline to an error message in the EC code.)

Some ECs may require a few microseconds to ramp up their clock after
being awaken by /CS assertion. This adds a Kconfig variable that can
be overridden at the mainboard-level which will force a delay between
asserting /CS and beginning a transfer.

The EC behavior for reading events from the ACPI interface was broken
with this commit:
d899fda lpc: ACPI query-next-event drops masked events
https://chromium-review.googlesource.com/194935
This is causing no EC wake events to be logged. To make sure they are
logged once again set the wake mask before querying for events.
Also remove the check for port80 event logging since this is no longer
used as we now store the port80 code in CMOS and this is unnecessary
commands to do for the resume path.

Coreboot needs to be able to reboot the PD controller into RO
image in recovery mode early in the boot process in order to
avoid a lengthy recovery mode boot if it is only done at vboot
software sync time.
In order to do this a new device index field is added to the
command structure which must be initaalized to zero for all EC
transactions.
This early init and image check code is only used in romstage so
include it in the __PRE_RAM__ block.

Depending on the transport mechanism for proto v3 different bytes
need to be send and/or read before the request and response. Depending
on the software and/or controller interface that requirement leads to
needing to copy data into temporary buffers. Avoid this by allowing
