mb/google/hatch: Use MEM_CH_SEL to indicate single_channel sku
MEM_CH_SEL is used to indicate whether we are on a single or dual
channel device, where MEM_CH_SEL = 1 for single channel skus and
MEM_CH_SEL = 0 for dual channel skus. Initialize single_channel field
(from GPP_F2), which will in turn initialize MemorySpdPtr pointers in
cannonlake soc code. In the first build, we did not use GPP_F2, so we
need to add an internal pulldown as those early devices were all dual
channel devices.
BUG=b:123062346, b:122959294
BRANCH=None
TEST=Boot into current boards and ensure that we have 2 channels as expected
Also, verify that GPP_F2 is set to 0.
