[PATCH v5 00/12] Input: xbox_gip - Add new driver for Xbox GIP

[Vicki Pfau <vi@endrift.com>]

This is a new version of the previously submitted xbox-gip series.

This introduces a new driver for the Xbox One/Series controller protocol,
officially known as the Gaming Input Protocol, or GIP for short.

Microsoft released documentation on (some of) GIP in late 2024, upon which
this driver is based. Though the documentation was incomplete, it still
provided enough information to warrant a clean start over the previous,
incomplete implementation.

This driver is already at feature parity with the GIP support in xpad,
along with several more enhancements:

- Proper support for parsing message length and fragmented messages
- Metadata parsing, allowing for auto-detection on various parameters,
  including the presence and location in the message of the share button,
  as well as detection of specific device types
- Controllable LED support
- HID passthrough for the Chatpad
- Battery information support
- Arcade stick support
- Racing wheel support
- Support for the security flow, allowing use with wireless controllers
  that include their own dongles. (This does not include support for the
  first-party dongle yet.)

The framework set out in this driver also allows future expansion for
specialized device types and additional features more cleanly than xpad.

Future plans include:

- Adding support for more device types, such as flight sticks.
- Exposing a raw character device to enable sending vendor-specific
  commands from userspace.
- Event logging to either sysfs or dmesg.
- Support for the headphone jack.

This version cleans up issues found by sashiko as well as some smaller
refactoring to clean up reused code.
