intel-gpio for v6.16-1

* Split GPIO ACPI quirks to its own file
* Refactored GPIO ACPI library to shrink the code

The following is an automated git shortlog grouped by driver:

gpiolib:
 -  acpi: Update file references in the Documentation and MAINTAINERS
 -  acpi: Move quirks to a separate file
 -  acpi: Add acpi_gpio_need_run_edge_events_on_boot() getter
 -  acpi: Handle deferred list via new API
 -  acpi: Make sure we fill struct acpi_gpio_info
 -  acpi: Switch to use enum in acpi_gpio_in_ignore_list()
 -  acpi: Use temporary variable for struct acpi_gpio_info
 -  acpi: Deduplicate some code in __acpi_find_gpio()
 -  acpi: Reuse struct acpi_gpio_params in struct acpi_gpio_lookup
 -  acpi: Rename par to params for better readability
 -  acpi: Reduce memory footprint for struct acpi_gpio_params
 -  acpi: Remove index parameter from acpi_gpio_property_lookup()
 -  acpi: Improve struct acpi_gpio_info memory footprint

The gpiolib-acpi.c is huge enough even without DMI quirks.
Move them to a separate file for a better maintenance.

No functional change intended.

Immutable branch between MFD, GPIO and NVMEM due for the v6.16 merge window

The Maxim MAX77759 is a companion PMIC for USB Type-C applications and
includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C
Port Controller (TCPC), NVMEM, and a GPIO expander.

This driver supports the GPIO functions using the platform device
registered by the core MFD driver.

Implement GPIO functionality which capable of setting pin as
input, output. Also, each pin can be used as interrupt which
support rising, falling, or both edge type trigger.

Blaize BLZP1600 GPIO controller is provided by VeriSilicon
Microelectronics based on the GPIO APB v0.2 design. It has 32
input/output ports which can be configured as edge or level
triggered interrupts. It also provides a de-bounce feature.
This controller is used on the Blaize BLZP1600 SoC.

Both gpio-sim and gpio-virtuser share a mechanism to instantiate a
platform device, wait for probe completion, and retrieve the probe
success or error status synchronously. With gpio-aggregator planned to
adopt this approach for its configfs interface, it's time to factor
out the common code.

Add dev-sync-probe.[ch] to house helper functions used by all such
implementations.

No functional change.

Add a driver to support the Polarfire SoC gpio controller. Interrupt
controller support is unavailable for now and will be added at a later
date.

FTDI FT2232H is a USB to GPIO chip. Sealevel produces some devices
with this chip. FT2232H presents itself as a composite device with two
interfaces (each is an "MPSSE"). Each MPSSE has two banks (high and low)
of 8 GPIO each. I believe some MPSSE's have only one bank, but I don't
know how to identify them (I don't have any for testing) and as a result
are unsupported for the time being.

Additionally, this driver provides software polling-based interrupts for
edge detection. For the Sealevel device I have to test with, this works
well because there is hardware debouncing. From talking to Sealevel's
people, this is their preferred way to do edge detection.
