smbios: Use SMBIOS 3.0 to support an address above 4GB
When the SMBIOS table is written to an address above 4GB a 32-bit table
address is not large enough.
Use an SMBIOS3 table in that case.
Note that we cannot use efi_allocate_pages() since this function has
nothing to do with EFI. There is no equivalent function to allocate
memory below 4GB in U-Boot. One solution would be to create a separate
malloc() pool, or just always put the malloc() pool below 4GB.
- Use log_debug() for warning
- Rebase on Heinrich's smbios.h patch
- Set the checksum for SMBIOS3
