[PATCH 2/3] Revert "kconfig: fix __enabled_ macros definition for invisible and un-selected symbols"

[Paul Gortmaker]

This reverts commit 953742c8fe8ac45be453fee959d7be40cd89f920.

Dumping two lines into autoconf.h for all existing Kconfig
options results in a giant file (~16k lines) we have to process
each time we compile something.  We've weaned IS_ENABLED()
and similar off of requiring the __enabled_ definitions so
now we can revert the change which caused all the extra lines.
