Documentation/flashing_firmware: Add info about SPI flash header
Some mainboards have a header connected to the SPI bus, which can be
used to connect a second flash chip and override the onboard flash. This
allows one to boot coreboot on the system without ever having to flash
the onboard flash. HP boards with this header all seem to use the same
2x8 or 2x10 header layout, so document the pinout.
