SMBIOS version check

As per SMBIOS specification(DSP0134) conformance guidelines, before

and SMBIOS version information.

Define Entry Point structure and implement SMBIOS version check
support.

Tested:
Verified BMC is able to validate the version information from the
SMBIOS table data which BIOS sends.
