This patch adds generic device information to the DMI table of the cros_ec_lpc driver, needed for Chromebooks/boxes using a custom coreboot firmware.
The DMI info would not contain "Google_*" as BIOS version string, instead the system vendor string would still be "GOOGLE", so this seems to be a reasonable match for every Chromebook/box running a custom firmware.
