[PATCH v16 0/4] HID: nintendo: Add preliminary Switch 2 controller driver

[Vicki Pfau <vi@endrift.com>]

This adds a new driver for the Switch 2 controllers. The Switch 2 uses an
unusual split-interface design such that input and rumble occur on the main
HID interface, but all other communication occurs over a "configuration"
interface. This is the case on both USB and Bluetooth, so this new driver
uses a split-driver design with the HID interface being the "main" driver
and the configuration interface is a secondary driver that looks up to the
HID interface, sharing resources on a common struct.

Due to using a non-standard pairing interface as well as Bluetooth
communications being extremely limited in the kernel, a custom interface
between userspace and the kernel will need to be designed, along with
bringup in BlueZ. That is beyond the scope of this initial patch, which
only contains the generic HID and USB configuration interface drivers.

This initial work supports general input for the Joy-Con 2, Pro Controller
2, and GameCube NSO controllers. IMU, rumble and battery support is not yet
present.

This should fix the last thing sashiko has been reporting that isn't
complete and utter nonsense. Unless anything seriously bad comes through
the next round, or a maintainer tells me I need to fix it, I'm just done.
