How image size limiting works in U-Boot should be easier to grasp if we
have all related options in one place.

The point of separate common/spl/Kconfig.tpl and common/spl/Kconfig.vpl
files is to group SPL / TPL / VPL symbols in those files .
There is "config TPL_" definitions literally all over the place. I think
there might actually even be more of them outside Kconfig.tpl than
inside.
That does not make it OK to make that situation worse.
This config TPL... should be in common/spl/Kconfig.tpl .
