[PATCH] platform/chrome: cros_ec_lpc: Add DMI definition for post-Skylake machines running custom Coreboot builds

[Alicja Michalska]

ChromeOS EC LPC lacks DMI match for newer machines, which
use "Google" DMI_SYS_VENDOR as opposed to "GOOGLE" in older models.
This patch adds DMI definition for MrChomebox's custom Coreboots builds,
which we (Chrultrabook Project) are using.
