x86: unification of i386 and x86_64 Kconfig.debug

Adding proper dependencies so the two Kconfig.debug files
are now identical and move the result file to x86.

-       depends on DEBUG_KERNEL
-       help
-	 Mark the kernel read-only data as write-protected in the pagetables,
-	 in order to catch accidental (and incorrect) writes to such const data.
-	 This option may have a slight performance impact because a portion
-	 of the kernel code won't be covered by a 2MB TLB anymore.
-	 If in doubt, say "N".

-       help
-         Force the IOMMU to on even when you have less than 4GB of
-	 memory and add debugging code. On overflow always panic. And
-	 allow to enable IOMMU leak tracing. Can be disabled at boot
-	 time with iommu=noforce. This will also enable scatter gather
-	 list merging.  Currently not recommended for production
-	 code. When you use it make sure you have a big enough
-	 IOMMU/AGP aperture.  Most of the options enabled by this can
-	 be set more finegrained using the iommu= command line
-	 options. See Documentation/x86_64/boot-options.txt for more
-	 details.
