cpuinfo is additional daemon, that actually do nothing with smbios, but
it can get some CPU-related information by using PECI interface. For
about couple of years PECI wasn't supported by upstream OpenBMC, the
implementation was only in Intel's fork.
I don't know actual situation, but I guess you just miss some libraries
for PECI support.
Anyway, you don't need this at this stage.

Yes, smbiosmdrv2 daemon reads SMBIOS information from the file
/var/lib/smbios/smbios2 and you have to somehow deliver it to the BMC
filesystem.

Not sure. I think I saw somewhere in the Internet example of delivering
it using phosphor-ipmi-blobs.

Well, it just parse SMBIOS tables from binary file and expose extracted
information to dbus for other daemons use.
