Subject: [PATCH] x86/Kconfig: avoid issuing pointless turned off
 entries to .config

Settings without prompts shouldn't normally have defaults other than Y,
as otherwise they (a) needlessly enlarge the resulting .config and (b)
if they ever get a prompt added later, the tracked setting of off will
prevent the devloper from then being prompted for his/her choice when
doing an incremental update of the configuration (make oldconfig).
