x86/kconfig: Move the ZONE_DMA entry under a menu

Move the ZONE_DMA kconfig symbol under a menu item instead
of having it listed before everything else in
"make {xconfig | gconfig | nconfig | menuconfig}".

This drops the first line of the top-level kernel config menu
(in 3.2) below and moves it under "Processor type and features".

          [*] DMA memory allocation support
              General setup  --->
          [*] Enable loadable module support  --->
          [*] Enable the block layer  --->
              Processor type and features  --->
              Power management and ACPI options  --->
              Bus options (PCI etc.)  --->
              Executable file formats / Emulations  --->
