Those defaults are not really needed, and they are not great as they
duplicate the dependencies of the options.

Instead, I've moved the "none" choice at the end, and just relied on
kconfig's behavior that consists in automatically selecting the first
choice that has its dependencies met.

Since they are mutually exclusive, I've changed this by a:

ifeq ...
...
else ifeq ...
...
else ifeq ...
...
endif

block.

Applied with those changes. Thanks!
