smbios: add funtion for smbios type17

Add smbios type 17 which can optionally be implemented
at the platform or mainboard level
In order to create SMBIOS type17, you will need to fill
memory_info data

BUG=None
BRANCH=None
TEST=Compile successfully on rambi and samus
     Boot to chromeOS on samus and rambi
