mainboard/google/poppy: Provide baseboard and variant concepts

In order to be able to share code across different poppy variants,
provide the concept of baseboard and variants. New directory layout:

variants/baseboard - code
variants/baseboard/include/baseboard - headers
variants/poppy - code
variants/poppy/include/variant - headers

New boards would then add themselves under their board name within
"variants" directory.

This is purely an organizational change.
