  3. smbios: Refactor SMBIOS library 

    Current SMBIOS library does not fully match to the specification.
It hardcodes values instead of exposing values from the device.
It does not support dynamic length for contained object handles
or elements and misses the handling of a few fields.

The refactoring of this patch includes:
1. Expose values from device via sysinfo interface.
2. Replace smbios_add_prop with smbios_add_prop_si to allow getting
   string values from sysinfo.
3. Add smbios_get_val_si to get int values from sysinfo.
4. Use sysinfo_get_data to get data area like contained object
   handles, elements or processor id.
5. Refactor SMBIOS cmd print functions to match the command output
   with the specification
6. Add new print functions for Type 0, 3 and 4.
7. Miscellaneous fixes in SMBIOS.
