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 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Change-Id: I7b7586b0ebfe7b2fd888f448a50ae086364fa718 Reviewed-on: https://review.coreboot.org/c/coreboot/+/44783 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
