Merlin was the name for the open-source variant of the EC. It
ended up getting entirely rewritten to work with SDCC, and is
currently being used on starbook/adl. The source code isn't
available at the time of this commit due to some old ITE XLT
code being used.
Add the latest version of the code, replacing the old code, so
the boards can be migrated over.

The command "git branch -a | grep -q ${branch}" may not exit with 0 when
pipefail is set. "grep -q" exits immediately with exit code 0 as soon as
a match is found. However, at that point "git branch -a" may be still
writing to the pipe, leading to SIGPIPE. When pipefail is set,
PIPESTATUS 141 will be returned. Fix the problem by not using "grep -q".
Also fix the branch name in the generated commit subject.

The use of a separate _PRW is not necessary when the _CRS interrupt
already has the Wake flag set (as these all do). Additionally, Windows
does not allow the use of a gpioint for the _PRW source, which results
in an ACPI_BIOS_ERROR BSOD.
Since ChromeOS builds for CYAN devices use an older kernel and may not
make use of _CRS interrupt Wake flag, keep the _PRW around when
CONFIG_CHROMEOS is selected.

Prior to commit d1c0f958d1 ("acpi: Call acpi_fill_ssdt() only for
enabled devices"), uart_inject_ssdt() was used to set the ACPI status
(_STA) for both enabled and disabled devices. The aforementioned commit
limited it to being called only on enabled devices, which left disabled
devices without any _STA method at all -- which the OS assumes means
that the device is present and enabled.
To fix this, create the _STA method in the UART asl code for each port,
and set the return value to a name variable (STAT) which defaults to
0 (not present/disabled). Then, have uart_inject_ssdt() set STAT to
present and enabled (0xF) for UARTs actually present on the board.
TEST=build/boot google/skyrim (frostflow), dump ACPI tables, and verify
that _STA returns 0xF only for UARTs enabled in devicetree.

For brya variants with a touchscreen, drive the enable GPIO high
starting in romstage while holding in reset, then disable the reset
GPIO in ramstage (done in the baseboard). This will allow coreboot
to detect the presence of i2c touchscreens during ACPI SSDT generation
(implemented in a subsequent commit).
