SMBIOS memory information missing on Denverton

Hello,

I'm using coreboot (a52b9c3a) on a Harcuvar CRB machine. The machine boots correctly however, the SMBIOS memory information are missing:

```
FSP_SMBIOS_MEMORY_INFO HOB
0x01: Revision
0x07: MemoryType
2400: MemoryFrequencyInMHz
1: DataWidth in bits
0x05: ErrorCorrectionType
0x01: ChannelCount
Channel 0
0x09: ChannelId
0x00: DimmCount
```

DimmCount shouldn't be 0 here. As a result, Tianocore is reporting 0GB of installed RAM whereas it is clear in the rest of the boot logs that the 8GB installed are detected. The full boot log is attached.

Thanks,

Mathieu
