Some Jasperlake Chromebooks overwrite the system vendor DMI value to the
name of the OEM that manufactured the device. This breaks Chromebook
quirk detection as it expects the system vendor to be "Google".

Add another quirk detection entry that looks for "Google" in the BIOS
version.

I would assume that platform that has DMI_SYS_VENDOR set to "Google", also has DMI_BIOS_VERSION set to "Google", so perhaps just replace DMI_SYS_VENDOR match with DMI_BIOS_VERSION, to keep table small? Or is that not a case?
