HID: wacom: Add pad buttons reporting on Intuos4 WL
This patch adds reporting of 1 wheel button and 8 strip buttons for Intuos4 WL. The buttons are reported as BTN_0 to BTN_9. The change of type butstate variable is required as the old type 'char' couldn't store state of 9 buttons. The change is not affecting Graphire tablet as it only uses first 2 bits of 'butstate'.
