x86: Provide default SMBIOS manufacturer/product

Add a file containing defaults for these, using the existing CONFIG
options. This file must be included with #include since it needs to
be passed through the C preprocessor.

Enable the driver for all x86 boards that generate SMBIOS tables.
Disable it for coral since it has its own driver.
