[coreboot] TXE and Descriptor bin management in Coreboot

Hi Mayuri,

The descriptor.bin file is relatively specific to each board.  This
sets the soft-straps, gives information about the ROM chip being used
on that particular board, and sets the sizes of the areas on the SPI
ROM.

As for the TXE/ME/SPS/xxx binary, this would be specific to the
CPU/SOC family at the very least.  Some chips will work with an ME
read off of a different board that has the same chip.  As I recall,
others chips have specific settings encoded in this binary as well as
in the descriptor.  This might just be for Xeon class chips, or it
might be more widespread at this point
