mb/prodrive/atlas: add unique DIMM locators in smbios type17
This patch adds unique device-locators, bank-locators and
asset-tags to the smbios type17 tables by making use of a
DIMMs controller-ID. This way we avoid name clashes when,
for example, two DIMMs share the same channel-ID and DIMM-ID
but have a distinct controller-ID.
