Kconfig: Refactoring of top-level Kconfig file
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.
