mb/google/poppy/variants/nami: Add field to identify single channel DDR
Variants of Nami need to accommodate single channel DDR. Will use
GPP_D10 on nami for identification. GPP_D10 will return 1 when device
is using single channel DDR and 0 when using dual channel DDR.
BUG=b:117194353
BRANCH=None
TEST=dmidecode | grep Channel and make sure that the correct number of
channels gets returned.
