Add touch.wake IDC property to control wakeup.

Normally we do not wake the device when the internal touch screen is
touched.  This behavior can now be configured by setting a property
in the input device configuration file.  Add the following line to
the IDC file to enable an initial touch to wake the device from sleep.

  touch.wake = 1
