[PATCH v2] Input: xpad - add support for generic clone X-Input gamepads

[Ishaan Dandekar <ishaan.dandekar@gmail.com>]

This device exposes a vendor-specific Xbox 360 interface (0283:0001)
but was previously ignored by the driver, causing it to fall back to
a generic hid interface. Adding its ID to xpad_device and xpad_table
allows it to initialize correctly as an X-Input gamepad.

Note to maintainers:
This device exposes a vendor-specific Xbox 360 interface (0283:0001). 
Adding its ID to xpad_device and xpad_table allows it to initialize 
correctly as an X-Input gamepad with full rumble support.

Context: This patch is a companion to a 2-patch series submitted to 
the linux-usb subsystem (v2: "Fix initialization for Generic Clone 
X-Input Gamepads"). The USB patches apply a 255-byte config request 
quirk to prevent this device's firmware from crashing. Once stabilized 
by the USB core, this xpad patch is required to actually route it 
properly. Both can be merged independently.

Changes in v2:
- Wrapped commit message at 72 columns.
- Separated from the USB series to target the input subsystem directly.
