soc/amd: Fix generating SMBIOS Type 17

soc/amd: Fix generating SMBIOS Type 17

The converter was setting SMBIOS values when dimm_info expects SPD
values.

dmidecode now shows the following:
Memory Device
        Array Handle: 0x0000
        Error Information Handle: Not Provided
        Total Width: 64 bits
        Data Width: 64 bits
        Size: 8192 MB
        Form Factor: SODIMM
        Set: None
        Locator: Channel-0-DIMM-0
        Bank Locator: BANK 0
        Type: DDR4
        Type Detail: Synchronous
        Speed: 933 MT/s
        Manufacturer: Hynix/Hyundai
        Serial Number: 00000000
        Asset Tag: Not Specified
        Part Number: HMAA51S6AMR6N-UH
        Rank: 1
        Configured Clock Speed: 933 MT/s
        Minimum Voltage: Unknown
        Maximum Voltage: Unknown
        Configured Voltage: Unknown

Example debug output:

  module_part_number(18): 'HMAA51S6AMR6N-UH  '

The serial number we get from AGESA (at least on my
board) is always 00000000. I'm assuming this is because the SPD info is
compiled in.

`mosys memory spd print all` is still failing though. I will look into
that next.
