Adds an HID driver for OneXPlayer HID configuration devices. There are
currently 2 generations of OneXPlayer HID protocol. The first (OneXPlayer
F1 series) only provides an RGB control interface over HID. The Second
(X1 mini series, G1 series, AOKZOE A1X) also includes a hardware level
button mapping interface, vibration intensity settings, and the ability
to switch output between xinput and a debug mode that can be used to debug
the button mapping. Some devices (G1 Series, APEX) use a hybrid of Gen1
RGB control and Gen 2 controller settings. To ensure there is no conflicts
when the driver is loaded, we skip creating the RGB interface for Gen 2
devices if there is a DMI match.

I'll also add a note that Gen 1 devices also have an interface for
setting the key map and debug mode, but that is done entirely over a
serial TTY device so it is not able to be added to this driver. There
are also some "Gen 0" devices (OneXPlayer 2 Series) also use it, but
the TTY interface also handles the RGB control so no support is
provided by this driver for those devices.

v2:
  - Add DMI quirks for certain devices that ship with both GEN1 and GEN2
    MCU to avoid clashing when initializing the RGB interface.
  - Add left & right vibration intensity attributes.
  - Add additional mappings for keyboard inputs.
  - Add a delayed work trigger to re-apply settings after the MCU
    completes initializing after a suspend/resume cycle.
