HID: wacom: Split apart 'wacom_setup_pentouch_input_capabilites'
This splits the 'wacom_setup_pentouch_input_capabilites' function into pieces dedicated to doing setup for just the pen interface and just the touch interface. This makes it easier to focus on the relevant piece when making changes. This patch introduces no functional changes.
