ec/compal/ene932: Update to use coreboot EC-mainboard API
This patch implements a simple interface between the EC and mainboard ASL code. This interface does not rely on the preprocessor, and prevents name conflicts by scoping the interface methods. As this interface is documented on the coreboot wiki, an in-tree documentation is not provided.
