HID: wacom: Unify speed setting
This patch unifies speed setting for both supported tablets. Functionality of "wacom_poke" (used only by Graphire) is now in "wacom_set_features". Reporting speed for both tablets can be changed by somethinkg like: echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed Accepted values: 0 - low speed, 1 - high speed. The way of changing reporting speed is the same for Graphire and Intuos4 WL.
