In order to support probing I2C devices when the controller is
in ACPI mode the mainboard needs to decalre them in the proper
scope with the address/interrupt information. The touchpad devices
are ATML0000/ELAN0000 and the touchscreen is ATML0001 so they can
be distinguished in userland scripts based on ID. There is also
a special "ISTP" node that indicates whether the devices is a
touchpad (=1) or touchscreen (=0) in case this is useful to drivers.
These names may not be final but they are a starting point and can
be easily changed.
Atmel devices also have a bootloader mode which needs to be
declared as a separate device. Unfortunately it does not work as
expected to have multiple I2cSerialBus() resources declared in a
single device and have it select properly, even with the use of
StartDependentFn(), so bootloader devices are declared separately.
The original devices are left in \_SB scope and are only enabled
if the I2C controllers are in PCI mode. The new devices are only
enabled if the I2C controllers are in ACPI mode.

This improves boot time in 2 ways for a firmware upgrade:
1. Normally MRC would detect the S0 state without an MRC cache
even though it's told to the S5 path. When it observes this
state a cold reset occurs. The cold reset stays in S5 for
at least 4 seconds which is time observed by the end user.
2. As the EC was running RW code before the reset after firmware
upgrade it will still be running the older RW code. Vboot will
then reboot the EC and the whole system to put the EC into RO
mode so it can handle the RW update.
The issues are mitigated by detecting the system is in S0 with
no MRC cache and the EC isn't in RO mode. Therefore we can do the
reboot without waiting the 4 secs and the EC is running RO so
the 2nd reboot is not necessary.

The memory reference code doesn't maintain some of
the registers which contain valuable information in order
to log correct reset and wake events in the eventlog. Therefore

BRANCH=rambi,squawks
TEST=Did various resets/wakes with logging patch which
consumes this structure. Eventlog can pick up reset
events and power failures.
