The issue with adding all options to debug.config is that if all options
are enabled at the same time, performance will take a huge hit.
Grouping the options by area will enable devs to only enable a subset of
configs. With this patch, you can just do "make pseries_mm_debug_defconfig"
to enable mm specific options for example.

I'm open to suggestions if there is a cleaner way to accomplish this.

Thanks,
