[U-Boot] [PATCH v4 06/20] Kconfig: fix SPL_FIT dependency

[Andre Przywara]

SPL_FIT obviously requires libfdt in SPL, so let Kconfig express that by
selecting SPL_OF_LIBFDT.
Also make the actual options that users want (SPL signature and SPL FIT
loading) visible in the menu and let them select the SPL_FIT as a
requirement.
Also remove the now redundant SPL_OF_LIBFDT from those Kconfigs that had
it in for the SPL FIT loading feature.
