kconfig: add a function to get the CONFIG_ prefix
Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means
the CONFIG_ prefix is hard-coded at compile time. This goes against
having a run-time defined CONFIG_ prefix.
Add a function that returns the CONFIG_ prefix to use (but keep the
current hard-coded behavior, to be changed in a later patch).
To avoid touching all the code that uses the CONFIG_ macro, we just
undef it, and define it to be a call to the function.
