mb/google/volteer: Add probed fw_configs to SMBIOS OEM strings 

Some Linux kernel drivers bind to "DMI quirks." In this case, the audio
fw_config is added as an OEM string, e.g., "AUDIO-MAX98357_ALC5682I_I2S"
so the audio topology can be correctly discovered.
But add all successfully probed fw_config items as well, because this
makes it easier to view what is selected from userspace.

BUG=b:161963281
TEST=With CBI FW_CONFIG field set to 0x201:

localhost ~ # dmidecode -t 11
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.

Handle 0x0009, DMI type 11, 5 bytes
OEM Strings
        String 1: DB_USB-USB4_GEN2
        String 2: AUDIO-MAX98373_ALC5682I_I2S
