soc/amd: Print dimm_info and TYPE17_DMI_INFO to help debug incorrect values

Example output:
  Handle: 1
  TotalWidth: 64
  DataWidth: 64
  MemorySize: 8192
  DeviceSet: 0
  Speed: 1200
  ManufacturerIdCode: 44416
  Attributes: 1
  ExtSize: 0
  ConfigSpeed: 933
  MemoryType: 0x1a
  FormFactor: 0xd
  DeviceLocator:   DIMM 0
  BankLocator:  CHANNEL A
  SerialNumber(8):  00000000
  PartNumber(20): HMAA51S6AMR6N-UH

  dimm_size: 0
  ddr_type: 0x1a
  ddr_frequency: 1200
  rank_per_dimm: 1
  channel_num: 0
  dimm_num: 0
  bank_locator: 0
  mod_id: 44416
  mod_type: 0x1a
  bus_width: 64
  serial(4): 0000
  module_part_number(23): HMAA51S6AMR6N-UH   ��@

dimm_size, mod_type, bus_width need to be updated so they return the
correct values. module_part_number is missing a null terminator due to
the AGESA part number being larger than the dimm_info buffer.

Example dmidecode output:

To enable the output set CONFIG_DEBUG_RAM_SETUP.

The Kconfig change is required in order to enable
CONFIG_DEBUG_RAM_SETUP, otherwise it's not a valid option.
