[PATCH] Input: xpad - add 8BitDo Ultimate 3-mode PID 201b

[Antoni Marzec]

The 8BitDo Ultimate 3-mode Controller for Xbox presents USB ID
2dc8:201b during normal 2.4 GHz operation.

There is currently no device-specific entry for this PID, so xpad
falls back to the "Generic X-Box pad" entry without MAP_SHARE_BUTTON.
As a result, pressing the Share button produces no evdev event.

The receiver transiently enumerates as 2dc8:200f while the wireless
connection is being established or has been lost. This PID already
has a device-specific xpad entry with MAP_SHARE_BUTTON. Once the
controller connects, the device re-enumerates as 2dc8:201b.

Add a device entry for 2dc8:201b with MAP_SHARE_BUTTON to expose the
Share button during normal operation.
