mb/google/volteer: move volteer devices to overridetree.cb
Move the following volteer-specific devices from baseboard's
devicetree.cb into volteer's overridetree.cb file:
- Goodix Touchscreen
- ELAN Touchscreen
- ELAN Touchpad
- SAR0 Proximity Sensor
Adjust the other variant's overridetree.cb files to correspond to
the changes made to the baseboard's devicetree.cb in this change.
BUG=b:159241303, b:154646959
TEST='emerge-volteer coreboot chromeos-bootimage', flash and boot
volteer to kernel and verify that the trackpad works.
