[RFC 0/6] rework sched_domain topology description

This patchset was previously part of the larger tasks packing patchset [1].
I have splitted the latter in 3 different patchsets (at least) to make the
thing easier.
-configuration of sched_domain topology (this patchset)
-update and consolidation of cpu_power
-tasks packing algorithm

Based on Peter Z's proposal [2][3], this patchset modifies the way to configure
the sched_domain level in order to let architectures to add specific level like
the current BOOK level or the proposed power gating level for ARM architecture.
