This change primarily moves the PowerResource up to a more common scope so
that the _PRx references are simpler. The ^ scope modifier isn't well
supported everywhere amongst OSes and drivers. Windows 10 will BSOD
early during boot with ACPI_BIOS_ERROR (code 0x6, which means it could
not find the object referenced by a _PRx) with the way things are currently
laid out).
I've also not seen a firmware outside of coreboot that tries to reference
count _ON and _OFF. Isn't it up to the OS to deference count, and whatever
it tells ACPI is what should happen (i.e., on means on and off means off)?
Some of the _UIDs are also duplicated. This change makes them unique.
A few cosmetic changes are made so that diffing cam0.asl against
cam1.asl has fewer extraneous differences.

For unused pins in octopus baseboard, configure them as GPIO input
and use the default termination. For the pins where board has an
external termination, remove SOC's internal termintation.

As per the ACPI specification, there are two types of power button
devices:
1. Fixed hardware power button
2. Generic hardware power button
Fixed hardware power button is added by the OSPM if POWER_BUTTON flag
is not set in FADT by the BIOS. This device has its programming model
in PM1x_EVT_BLK. All ACPI compliant OSes are expected to add this
power button device by default if the power button FADT flag is not
set.
On the other hand, generic hardware power button can be used by
platforms if fixed register space cannot be used for the power button
device. In order to support this, power button device object with HID
PNP0C0C is expected to be added to ACPI tables. Additionally,
POWER_BUTTON flag should be set to indicate the presence of control
method for power button.
Chrome EC mainboards implemented the generic hardware power button in
a broken manner i.e. power button object with HID PNP0C0C is added to
ACPI however none of the boards set POWER_BUTTON flag in FADT. This
results in Linux kernel adding both fixed hardware power button as
well as generic hardware power button to the list of devices present
on the system. Though this is mostly harmless, it is logically
incorrect and can confuse any userspace utilities scanning the ACPI
devices.
This change gets rid of the generic hardware power button from all
google mainboards and relies completely on the fixed hardware power
button.

TEST=Verified that fixed hardware power button still works correctly
on nautilus.

Logic: If vboot is not used and the tpm is not initialized in the
romstage makes use of the ramstage driver to initialize the TPM
globally without having setup calls in lower SoC level implementations.
* Add TPM driver in ramstage chip init which calls the tpm_setup
function.
* Purge all occurrences of TPM init code and headers.
* Only compile TIS drivers into ramstage except for vboot usage.
* Remove Google Urara/Rotor TPM support because of missing i2c driver
in ramstage.
