Hi folks,

This stems from Barry introducing a new CONFIG_SCHED_CLUSTER which highlighted
the current state of similar Kconfigs isn't great:
  http://lore.kernel.org/r/CAGsJ_4xZD0sG0Df666f0bvHOzuPMjnw0dN_mArER5k1pJ6LPLw@mail.gmail.com

The changes happen all in one big patch; the alternative would be to have one
patch per arch that adds the ARCH_SUPPORTS_SCHED_* selection, then a final patch
that adds the generic definitions and removes the arch ones (which I can do if
that's a preferred approach).

Briefly tested by setting ARCH=foo and playing around with menuconfig.

Based on top of Peter's queue:
  git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git -b sched/next

Patches are also available at:
  https://git.gitlab.arm.com/linux-arm/linux-vs.git -b mainline/sched/topo_kconfig_cleanup

Cheers,
Valentin
