util/supermicro: Add and use new tool smcbiosinfo
The BMC and tools interacting with it depend on metadata placed inside
the ROM in order the flash the BIOS.
Add a new tool smcbiosinfo, integrate it into the build system, and
generate a 128byte metadata file called smcbiosinfo.bin on build.
You need to provide the BoardID for every SMC mainboard through a new
Kconfig symbol: SUPERMICRO_BOARDID
Some fields are unknown, but it's sufficient to flash it using SMC
vendor tools.
Tested on Supermicro X11SSH:
* Flashing using the WebUI works
* Flashing using SMCIPMITool works
No further validation is done on the firmware.
