mainboard/google/poppy: 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.
