spl: support TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE via Kconfig
Let's clean up behind ourselves and move the (newly defined)
TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE into Kconfig. Given that
0x0 might be considered to be valid values for TPL_TEXT_BASE and
TPL_STACK, we need to introduce helper config options
("TPL_NEEDS_SEPARATE_...") to indicate that these symbols are used
(and not inherited from their SPL variants) for any given
target-platform.
