Some devices cann't use SPL framework at TPL stage, but the
CONFIG_SPL_FRAMEWORK is still defined at TPL stage, so need
to separate them with CONFIG_TINY_TPL.
If the SPL framewrok was used both at TPL and SPL stage,
CONFIG_TINY_TPL is not defined.
If the SPL framewrok was used at SPL stage, but not use at
TPL, need to define CONFIG_TINY_TPL.
