Add architecture specific funtions for setting up SMBIOS and runtime services data structures. These are not fundamentally x86 specific, but ARM currently lacks implementations. These functions may not be needed when ARM SMBIOS and runtime service support is added. Both SMBIOS and EFI runtime service support depend on this EFI boot patch series.
