whiskers touchpad: adjust value range
1. In usb_hid_touchpad.h, `pressure` is defined as unsigned:10, while in
touchpad_st.h, `z` is defined as unsigned:8, scale it up to match
size of `pressure`.
3. Scale up `width` and `height` for similar reason.
2. Update physical dimension, so it match the real device.
With this change, I can use EC touchpad on my Linux machine.
