lib: spl: differentiate between TPL and SPL for libfdt/of_control/of_platdata

This splits the compilation of code modules for TPL and SPL for
OF_CONTROL (and related) features between TPL and SPL.  The typical
use-case of this is a TPL stage that uses OF_PLATDATA at TPL and
provides full OF_CONTROL at SPL (e.g. on the RK3368).
