usb: core: add quirk for Alcor Link AK9563 smartcard reader
commit 303e724d7b1e1a0a93daf0b1ab5f7c4f53543b34 upstream.
The Alcor Link AK9563 smartcard reader used on some Lenovo platforms
doesn't work. If LPM is enabled the reader will provide an invalid
usb config descriptor. Added quirk to disable LPM.
Verified fix on Lenovo P16 G1 and T14 G3
