mainboard/google/zoombini: Provide memory configuration variant API
Add support for memory configuration by providing weak implementation
from the baseboard. All SPD files are present under spd/
directory. SPD_SOURCES must be provided by the variants to ensure
that required SPD hex files are included in the SPD binary.
BUG=b:64395641
BRANCH=None
TEST=Verify "./util/abuild/abuild -p none -t google/zoombini -x -a"
compiles successfully.
