We currently have fields in struct cpuinfo_mips for the core & VP(E) ID
of a particular CPU, and various pieces of code directly access those
fields. This patch abstracts such access by introducing accessor
functions cpu_core(), cpu_set_core(), cpu_vpe_id() & cpu_set_vpe_id()
and having code that needs to access these values call those functions
rather than directly accessing the struct cpuinfo_mips fields. This
prepares us for changes to the way in which those values are stored in
later patches.
The cpu_vpe_id() function is introduced even though we already had a
cpu_vpe_id() macro for a couple of reasons:
1) It's more consistent with the core, and future cluster, accessors.
2) It ensures a sensible return type without explicit casts.
3) It's generally preferable to use functions rather than macros.

The correct position is topology.h, and this fix macros redefinition
problems for Netlogic.
[[email protected]: Fix build - the original patch broke most
configurations.]

Remove mc_capable() and smt_capable(). Neither is used.
Both were added by 5c45bf279d37 ("sched: mc/smt power savings sched
policy"). Uses of both were removed by 8e7fbcbc22c1 ("sched: Remove stale
power aware scheduling remnants and dysfunctional knobs").

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.
