HID: yurex: recognize GeneralKeys wireless presenter as generic HID

Unfortunately, the device seems to have the same Vendor ID and Product ID
as YUREX leg-shakes sensors, and the commit 6bc235a2e2 ("USB: add driver
for Meywa-Denki & Kayac YUREX") added the ID to hid_ignore_list.

I believe that we can distinguish YUREX and the Wireless Presenter by
device type.  The patch below makes the driver ignore only YUREX
(bInterfaceProtocol==0), and recognize Wireless Presenter
(bInterfaceProtocol is keyboard or mouse) as generic HID.  (I don't have
the Wireless Presenter, so not yet ested.)
