[PATCH] x86_64: Make ACPI NUMA and NUMA emulation peers of K8_NUMA in Kconfig

[PATCH] x86_64: Make ACPI NUMA and NUMA emulation peers of K8_NUMA in Kconfig

On x86_64 arches, there is no way to choose ACPI_NUMA without having to choose
K8_NUMA.  CONFIG_K8_NUMA is not needed for Intel EM64T NUMA boxes.  It also
looks odd if you have to select ACPI_NUMA from the power management menu.
This patch fixes those oddities.  Patch does the following:

1. Makes NUMA a config option like other arches
2. Makes topology detection options like K8_NUMA dependent on NUMA
3. Choosing ACPI NUMA detection can be done from the standard
   "Processor type and features" menu

AK: I fixed up the dependencies and changed the help texts a bit
on top of Kiran's patch.
