The USE_TINY_PRINTF symbol only changes things within SPL and TPL builds, so make it depend on that support. Next, make it default as within these cases we should rarely have need of more advanced print formats outside of the debug context. To do this, in a few cases we need to correct our Kconfig dependencies as we had cases of non-SPL targets select'ing this symbol. Finally, in the case of a few boards we really do need the full printf functionality. Signed-off-by: Tom Rini <trini@konsulko.com>
