Now that Crust (SCP firmware) has support for H3, we need a FIT image to load it. H3 also needs to load a SoC-specific eGon blob to support CPU 0 hotplug. Let's first enable FIT support before adding extra firmware.
Update the binman description to work on either 32-bit or 64-bit SoCs: - Make BL31 optional, since it is not used on 32-bit SoCs (though BL32 may be used in the future). - Explicitly set the minimum offset of the FIT to 32 KiB, since SPL on some boards is still only 24 KiB large even with FIT support enabled. CONFIG_SPL_PAD_TO cannot be used because it is not defined for H616.
FIT unlocks more features (signatures, multiple DTBs, etc.), so enable it by default. A10 (sun4i) only has 24 KiB of SRAM A1, so it needs SPL_FIT_IMAGE_TINY. For simplicity, enable that option everywhere.
