Input: xpad - rename QH controller to Legion Go S

commit 659a7614dd72e2835ac0b220c2fa68fabd8d1df9 upstream.

The QH controller is actually the controller of the Legion Go S, with
the manufacturer string wch.cn and product name Legion Go S in its
USB descriptor. A cursory lookup of the VID reveals the same.

Therefore, rename the xpad entries to match.
