mb/intel/adlrvp: Add probed fw_configs to SMBIOS OEM strings 

This feature was added in ADL-M RVP for discovering correct
audio topology using OEM string e.g., "ADL_MAX98373_ALC5682I_I2S"
for discovering boards having audio expansion card

Bug=None
Test= With CBI FW_CONFIG set to 0x100

localhost /home/root # dmidecode -t 11
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.

Handle 0x0009, DMI type 11, 5 bytes
OEM Strings
        String 1: ADL_MAX98373_ALC5682I_I2S
