amd/gardenia: Correct SPD AGESA callout
Gardenia makes no special considerations for a board_id regarding SPD access and addressing. Remove this from the source and use the standard AGESA call. Make SPD address changes to devicetree.cb. Note that Gardenia is designed to be a two channel, single DIMM/channel system (some SKUs with two DIMMs on the second channel). However, this port is for the Stoney processor which is a single channel. As a result, the second DIMM slot is not usable. A future improvement could involve a port using a different processor, with unique devicetree files for each.
