Now that 32-bit SoCs can load U-Boot proper (and possibly other firmware) from a FIT, use this method by default. SPL_FIT_IMAGE_TINY is required to stay within the 24 or 32 KiB SPL size limit on early SoCs; for consistency, enable it everywhere.

Crust (SCP firmware) has support for A33 and H3, and H3 also needs to load an eGon blob to support CPU 0 hotplug (a silicon bug workaround). 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 consistency, enable that option everywhere. After this series is applied, we can increase SPL_MAX_SIZE for H6 and newer SoCs, both 32-bit (e.g. A50, T113) and 64-bit. I did not do that yet because there is some discussion to be had about the correct value: it must be adjusted to guarantee return-to-FEL functionality, and the exact adjustment depends on the sunxi-fel tool implementation.
