Subject: [PATCH v1] ALSA: hda: intel-dsp-config: Fix JSL Chromebook quirk detection

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.
