This change adds support for the generic LPC memory range configuration
in the EC ACPI code.
If CONFIG_EC_GOOGLE_CHROMEEC_LPC_GENERIC_MEMORY_RANGE is enabled, the
EC will use the generic LPC memory range for EMEM related communication
between EC and AP Firmware. This is useful for platforms that do not
have a dedicated IO range like accessed EMEM through port 62/66 or
through LPC at 900h.
The generic LPC memory range is defined by the _SB.PCI0.LPCB.GLGM()
method. This method returns the base address and size of the memory
range.

This commit introduces a new function,
google_chromeec_is_barrel_charger_present(), which checks if a barrel
charger is present.
The function uses the following logic to determine if a barrel charger
is present:
- If both a barrel charger and USB-C PD are present, then the barrel
charger takes precedence over USB-C PD. As a result,
google_chromeec_is_usb_pd_attached() will return false. This logic can
be used to deterministically say if a barrel charger is present even
when both a barrel charger and USB-C PD are attached.
- If an AC charger is detected and USB-C PD is not present, then a
barrel charger must be present.
This change allows the EC to accurately detect the presence of a barrel
charger, even when a USB-C PD charger is also attached.

This patch adds a new API `google_chromeec_is_below_critical_threshold()
` to check if the battery level is below the critical threshold.
The API uses the existing `ec_cmd_battery_get_dynamic()` command to
retrieve the battery flags and checks the `EC_BATT_FLAG_LEVEL_CRITICAL`
flag to determine if the battery level is critical.
This API can be used by other components to query the battery critical
status and take necessary actions, for example, while the system is
booting with low battery fuel with and/or without an AC
charger attached.
This addresses the need to implement a low battery charger icon and
detect when the system is booting with low battery fuel. The existing
`google_chromeec_is_battery_present_and_above_critical_threshold()`
API is not suitable for this purpose because any negative decision
(like battery not present and/or battery is critically low) implemented
around this existing API will also render the lower battery indicator
when the system is booting into battery cut-off mode. Ideally, we do not
wish to render any icon and simply allow boot to the OS during system
battery cut-off boot.

The GPIO value is returned to the HID driver via the `_STA` and

This was verified with ACPI debug enabled, as dmesg does not

The Chrome EC currently supports two ways to read battery strings on
ACPI platforms:
* Read up to 8 bytes from EC shared memory BMFG, BMOD, ...
* Send a EC_CMD_BATTERY_GET_STATIC host command and read strings from
the response. This is assumed to be exclusively controlled by the OS,
because host commands' use of buffers is prone to race conditions.
To support readout of longer strings via ACPI mechanisms, this change
adds support for EC_ACPI_MEM_STRINGS_FIFO (https://crrev.com/c/5581473)

limited to 64 characters in the implementation) from the EC and to

Under Windows ACPI, GpioInt and _PRW must be mututally exclusive within
the scope of a device, otherwise a BSOD occurs with an ACPI_BIOS_ERROR.
To enforce this, only use _PRW when EC_ENABLE_SYNC_IRQ_GPIO is not set.
If both EC_ENABLE_WAKE_PIN and EC_ENABLE_SYNC_IRQ_GPIO are set, then
ensure that the GpioInt is flagged as ExclusiveAndWake (vs just
Exclusive) so that the CREC device is still able to wake the device
as needed.
TEST=Build/boot google/{nocturne,frostflow} to Win11 w/ sync_irq_gpio
and wake_pin both enabled.

If the EC doesn't know a value, it will report it as 0xffff. In these
cases, calculate a value to used based on others. For example, if the
EC doesn't know the last full charge capacity, report the design
capacity to the OS.

The battery remaining percentage is a uint16_t, so correct this in
the EC memory. This change is non-function, as the EC is little
endian.

Initial commit is a copy of ec/system76/ec from tag v24.02.1 (commit
0a280ff7) with string changes. Dasharo-specific features will be added
in subsequent commits, similar to how Librem EC support was added in
changes 52390 and 52391.

<stdio.h> header is used for input/output operations (such as printf,
scanf, fopen, etc.). Although some input/output functions can manipulate
strings, they do not need to directly include <string.h> because they
are declared independently.
