HID: wacom: Enable pad device for older Bamboo Touch tablets

Commit 862cf55 neglected to set the WACOM_DEVICETYPE_PAD flag for older two-finger Bamboo Touch tablets. Not only does this result in the pad device not appearing when such a tablet is plugged in, but also causes a segfault when 'wacom_bpt_touch' tries to send pad events. This patch adds the flag to resolve these issues.
