usb_hid_touchpad: make max pressure configurable
Maximum pressure is now defined by
CONFIG_USB_HID_TOUCHPAD_LOGICAL_MAX_Z.
`hammer` is the only board using usb_hid_touchpad, the board.h is
updated to reflect the change (for old boards "HAMMER" and "STAFF", we
keep the value 1023, so they should behave the same).
