Subject: [PATCH v3 3/4] riscv: obtain SMBIOS entry from FFI

On RISC-V, Coreboot does not support EFI booting, only supports
devicetree, and RISC-V does not have reserved address segments.
To support Coreboot on RISC-V platforms that require DMI
functionality, SMBIOS entry need to be passed through FFI.
