ASoC: SOF: sof-pci-dev: Fix community key quirk detection

commit 7dd692217b861a8292ff8ac2c9d4458538fd6b96 upstream.

Some Chromebooks do not populate the product family DMI value resulting
in firmware load failures.

Add another quirk detection entry that looks for "Google" in the BIOS
version. Theoretically, PRODUCT_FAMILY could be replaced with
BIOS_VERSION, but it is left as a quirk to be conservative.
