chromeos-bsp-quawks : Add wakeup_input_device_names with tpad wake

Add support for configuring Elan touchpad. This preference
file will tell the power manager to set the Elan trackpad device
to wakeup "enabled" before suspending with lid open and wakeup
"disabled" before suspending with lid closed.

BUG=chrome-os-partner:27808
TEST=powerd_dbus_suspend
Touch the touchpad.
Check that quawks wakes from suspend.
Use a magnet to trigger quawk's hall effect sensor.
Check that squawks does not wake when touching the touchpad.
