Change subject: soc/intel/tigerlake: Hook up FSP repository
......................................................................

Patch Set 7:
> > I can only give a +1 because there's a Tigerlake UP3 reference board in the tree, which would need the IOT version of FSP.
> >
> > For reference, UP3: IOT, UP4: Client.
>
> Oh, yes. Thanks! I am not sure if UP4 is the Client version (the FSP repo doesn't mention UP4 anywhere), but some news sites are saying so.
>
> So I would just add another Kconfig option for differentiation UP3 / UP4.
>
> What should I use for the extension? UP3 / UP4 or IOT / CLIENT?

_IOT vs _CLIENT sounds good.
