[PATCH] HID: add support for 0079:1846 Mayflash/Dragonrise USB Gamecube Adapter

["Wladimir J. van der Laan" <laanwj@gmail.com>]

From: Ethan Warth <redyoshi49q@gmail.com>

Mayflash/Dragonrise seems to have yet another device ID for one of their
Gamecube controller adapters.  Previous to this commit, the adapter
registered only one /dev/input/js* device, and all controller inputs (from
any controller) were mapped to this device.  This patch defines the 1846
USB device ID and enables the HID_QUIRK_MULTI_INPUT quirk for it, which
fixes that (with the patch, four /dev/input/js* devices are created, one
for each of the four controller ports).

This patch is not my work but a direct repost of
https://lore.kernel.org/lkml/CAAPc1Th4mgE=ntLY=NXn2Jbfgi0OBpZ5R2sYGhWJ_4+syuPA9w@mail.gmail.com/T/.

The original patch was not merged due to a line break issue. I have corrected this.

I have tested it against current master as well as ubuntu focal's 5.4.0,
and it works, it separates the adapter into four different evdev devices,
making it usable in Linux. It also enables rumble (which I have not tested due to lack
of a capable controller).
