[PATCH] target/arm: build smbios 19 table

[Mihai Carabas]

Use the base_memmap to build the SMBIOS 19 table which provides the address
mapping for a Physical Memory Array (from spec [1] chapter 7.20).

This was present on i386 from commit c97294ec1b9e36887e119589d456557d72ab37b5
("SMBIOS: Build aggregate smbios tables and entry point").
