If a UCSI event comes in when the EC is in S0ix mode then the kernel
driver attempts a transaction but fails and this can leave the system
in an unexpected state where the only wake source is the power button.
This change will not notify the UCSI driver if the EC is in S0ix mode
and instead keep track of the event and send it on resume.

TEST=tested on drallion system:
1. Put drallion system into suspend
2. Attach power supply
3. Ensure the system can wake with keypress

According to the Wilco EC spec the BTSC bit of PWSR is always cleared
when PWSR is read so that battery status change events are only
triggered one time. Testing of the Wilco EC has verified this behavior.
This changes the way in which the battery status change bit is used from
checking the bit state against the previous value to always issuing a
battery event when the BTSC bit is set. The other bits in PWSR indicate
state directly and do not behave like the BTSC bit.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

This change adds support for the UCSI specification in order to
provide information about the Type-C port and an interface to
perform power and data role swap.
This change is split across the DSDT and SSDT, with the shared
memory and operation region declared in the SSDT after being
allocated in CBMEM.
The OS will fill in the registers in the system memory region and
then call the _DSM method wtih a read or write argument. The DSM
method will copy the required registers to/from the system memory
and the EC and perform the write or read action.
Responses from the EC will generate a new SCI with event code 0x79
which will notify this UCSI ACPI device and the OS driver will take
action to read status from the EC.

Add an ACPI device that is compatible with the Intel Virtual
Button kernel driver for reporting tablet mode state and various
virtual button events that may come from the EC.
This driver is used in Windows and in the Linux kernel at
drivers/platform/x86/intel-vbtn.c
Because of a check in the kernel driver it expects the board to
define the SMBIOS enclosure type as convertible for the check at
driver load time for tablet/laptop and dock/undock to work.
The virtual tablet mode button will proxy the tablet mode state
sent from the Sensor Hub to a SW_TABLET_MODE event in the kernel.
The virtual power button is used during S0ix for the EC to wake
the system with an SCI. There are separate press and release
events which are sent for completeness, although the kernel driver
will ignore the release event.
BUG=b:73137291
TEST=Test that the power button can wake the system from S0ix.
Also verify that the device is reported as laptop mode at boot.

done with ACPI and not mailbox calls this will be implemented as a

There is a dependency issue with the EC DPTF code accessing
methods that are external, but once the mainboard includes the
relevant code they become internal and the current version of
IASL used by jenkins will fail to compile it.
Until the new IASL is deployed everywhere wrap the EC DPTF code
and expect that the mainboard will explicitly enable it.

Add the support needed for DPTF. This includes the methods to
write trip point values, read temperatures, and handle events.
This was tested on a sarien board by inspecting AML debug output
with the kernel while monitoring temperatures and trip points in
sysfs and controlling temperatures with a fan to ensure that when
a trip point is crossed an SCI is generated and the event is
handled properly.

Extended events will be handled by the OS kernel driver, but that
driver needs a method exposed by ACPI to read the event data from
the EC and into a buffer.
Tested by generating a hotkey event and reading the buffer from
the Linux kernel driver with acpi_evaluate_object().
