Some refactoring of the top-level Kconfig file which includes:
* using "if" to remove numerous identical dependency tests
* reordering config entries to group related ones
* spelling and grammar fixes
There should be no functional changes, only aesthetic ones.

AFAICT, there should be no functional difference, but i'm willing to
be corrected.
