SMBIOS entries for manufacturer and board can't be empty, as the spec explicitly requires a value. Instead of passing "Unknown" and "Unknown product" for the manufacturer and product name if the .dts options are missing, try to use CONFIG_SYS_VENDOR and CONFIG_SYS_BOARD respectively. If those are not found either warn the user at runtime and use "Unknown" for both entries.
