x86: use sysfs DMI information to populate sysinfo
Use the DMI data available in sysfs to extract manufacturer and model info and write it to /tmp/sysinfo/. The data will be picked up by board_detect and can be used by e.g. LuCI to display a more appropriate model description. On an APU board the files will contain the following values: # cat /tmp/sysinfo/model PC Engines APU # cat /tmp/sysinfo/board_name pc-engines-apu Signed-off-by: Jo-Philipp Wich <jo@mein.io>
