soc/intel: Add node_num to dimm_info struct + adjust dimm_info_fill
The dimm_info structure (defined in src/include/memory_info.h)
currently does not hold information about the DIMM's
node/controller ID.
This patch extends the dimm_info structure by adding a new field for
the node ID, called node_num. Also, adapt the dimm_info_fill()
function accordingly to populate the newly-added field.
Background: These changes are necessary for the Atlas mainboard, where
we are currently experiencing issues with the DIMMs device/bank
locator. Our 2 DIMMs share the same CHANNEL and DIMM ID but have a
distinct NODE ID. By looking at the smbios table we see
Channel-0-DIMM-0 for both DIMMs. Thus, we need their NODE IDs in order
to distinguish them.
This patch was tested by building and booting for the Alderlake-P
RVP board, which has the same DIMM slot configuration as the
Prodrive Atlas mainboard.
