Add Wacom touch FW updater script
This CL adds a touch firmware updater script for Wacom touch sensors.
This checks the firmware version on disk and compares it to the current
active FW version on the touch IC and updates it accordingly. The
actual updates are performed using a commandline tool called
wacom_update.
CQ-DEPEND=CL:372327
BUG=chromium:624262
TEST=Deployed on a device including a Wacom touchscreen and rebooted,
the firmware script updates the firmware when needed and chooses not to
when the firmware version is up to date.
