SBE: Send OPAL relocated base address to SBE
OPAL relocates itself during boot. During memory preserving IPL hostboot needs to access relocated OPAL base address to get MDST, MDDT tables. Hence send relocated base address to SBE via 'stash MPIPL config' chip-op. During next IPL SBE will send stashed data to hostboot... so that hostboot can access these data.
