Fingerprint interrupt (FPMCU_INT_L) is level triggered and not edge
triggered. Also, we are using GEVENT for wake from fingerprint and
not the GPIO IRQ wake. Thus, the irq property exposed in ACPI tables
does not need to be set to indicate wake for the IRQ.
This change updates GPIO table to configure the pad as level triggered
and drops the wake attribute for irq_gpio in overridetree.
BUG=b:165612778
BRANCH=zork
TEST=Verified that fingerprint still works in S0 and to wake device
from S3.

This reverts commit 81066b7ce7192432389578fc0f15b3a46da84bad.
Reason for revert: The hang observed when not exposing the reset GPIOs was root caused to zork sharing the same I2C bus between touchscreen and touchpad and interleaving of messages during probe which resulted in incorrect information returned back by touchscreen firmware. Exposing the reset GPIO changed the timing of probe and hence helped workaround the hang issue. The touchscreen driver is now fixed to perform I2C transactions in a single transfer and so the hang is no longer observed when reset GPIO isn't exposed.

The USB OC pin mapping is similar enough to move it to the base board
and just have two overrides for trembyle, which is based on an older
version of the schematics, and one override for woomax, which doesn't
use one USB port.

This reverts the code from commit 728c0787f2 that removes the reset
GPIO from the touchscreen ACPI interface.
That patch exposes a bug which leads to an invalid opcode trap in the
touchscreen code. Reverting this gets the system working again, but is
not a long-term solution.

v3.6 of reference schematics have switched the polarity of reset
signal to touchscreen controller from active high to active low. This
change updates the default configuration in baseboard gpio tables to
set the reset GPIO to output low and override tables in variants to set the
reset GPIO to output high. Additionally, devicetree by default exposes
ACTIVE_LOW configuration for reset GPIO. In order to support pre-v3.6
boards, reset GPIO is updated to ACTIVE_HIGH based on board version.

The Raydium ACPI entry currently provides a reset GPIO and an _ON/_OFF
method to the kernel. These are contradictory. The ownership of the GPIO
should be mutually exclusive between either the OS or the FW. Since we
have two methods exposed this causes the OS to reset the TS twice. Once
using the _ON method, and once using the GPIO. Additionally the _ON
method is waiting for 20ms after reset while the OS driver uses a 50ms
delay. The Raydium TS datasheet specifies 20ms for FW ready time, so the
OS driver is adding additional padding.
The reference design has a 32ms rise time on the reset line. So without
this patch, the OS tries to reset the TS using the _ON method and it
waits for 20ms. This is not enough time for the reset line to reach
high, let alone account for the FW ready time. The OS driver then tries
to reset the device by toggling the GPIO. It waits 50ms which is still
2ms less than required.
This CL removes the GPIO from being exported in the _CRS so the OS
driver won't try and reset the device. It also increases the reset delay
by 32ms to account for the rise time.
This isn't a complete fix. I think that the slow rise time is causing
some kind of metastability in the TS reset hardware. Using a script to
bind and unbind the TS driver, the TS device becomes unresponsive after
~200 iterations. The only way to reset the device is to power cycle.
The TS power is also not currently controlled by the power resource.
This means that we have no guarantee over when the reset line is
toggled. This will lead to issues while spending and resuming.

This information is redundant since it's already specified in
baseboard/devicetree_trembyle.cb or baseboard/devicetree_dalboz.cb
domain 0 is still required because sconfig uses it as an identity anchor

This is a copy of the mb/google/zork directory from the chromiumos
coreboot-zork branch. This was from commit 29308ac8606.
See https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/29308ac8606/src/mainboard/google/zork
Changes:
* Minor changes to make the board build.
* Add bootblock.c.
* Modify romstage.c
* Removed the FSP_X configs from zork/Kconfig since they should be
set in picasso/Kconfig. picasso/Kconfig doesn't currently define the
binaries since they haven't been published. To get a working build
a custom config that sets FSP_X_FILE is required.
