mb/google/poppy: Add variant support for camera asl

This change adds infrastructure to allow variants to define their own
camera.asl file.
- Poppy and soraka use the one provided by baseboard.
- Dummy file is added for nautilus since it does not have camera
support enabled yet.

TEST=Verified that DSDT table remains the same with and without this
change.
