[PATCH 3/3] lib: smbios: Detect system properties via SYSINFO IDs

Code is pretty much supports only DT properties and completely ignore
information coming from sysinfo driver.
Code is calling smbios_add_prop() which calls with
smbios_add_prop_si(SYSINFO_ID_NONE). But SYSINFO_ID_NONE can't
differentiate different entries from sysinfo driver.
That's why introduce separate SYSINFO macros which can be used in sysinfo
driver and passed to smbios structure.
