sysinfo: Provide a default driver to set SMBIOS values
Some boards want to specify the manufacturer or product name but do not
need to have their own sysinfo driver.
Add a default driver which provides a way to specify this SMBIOS
information in the devicetree, without needing any board-specific
functionality.
