drivers/ipmi: Add Supermicro OEM commands
Add a new driver for OEM commands an select if from x11-lga1151-series.
The driver communicates the BIOS version and date to the BMC using OEM commands. The command should be supported on all X11 series, but might work with older BMC, too.
Tested on X11SSH-TF: The BIOS version strings are updated on boot and are visible in the BMC web UI.
