ARM: 7011/1: Add ARM cpu topology definition

The affinity between ARM processors is defined in the MPIDR register.
We can identify which processors are in the same cluster,
and which ones have performance interdependency. We can define the
cpu topology of ARM platform, that is then used by sched_mc and sched_smt.

The default state of sched_mc and sched_smt config is disable.
When enabled, the behavior of the scheduler can be modified with
sched_mc_power_savings and sched_smt_power_savings sysfs interfaces.

Changes since v4 :
*  Remove unnecessary parentheses and blank lines

Changes since v3 :
* Update the format of printk message
* Remove blank line

Changes since v2 :
* Update the commit message and some comments

Changes since v1 :
* Update the commit message
* Add read_cpuid_mpidr in arch/arm/include/asm/cputype.h
* Modify header of arch/arm/kernel/topology.c
* Modify tests and manipulation of MPIDR's bitfields
* Modify the place and dependancy of the config
* Modify Noop functions

sched: Ensure cpu_power periodic update

With a lot of small task, the softirq sched is nearly never called
when no_hz is enable. Te load_balance is mainly called with
the newly_idle mode which doesn't update the cpu_power.
Add a next_update field which ensure a maximum update period when
there is short activity

ARM: cpu topology: add debugfs
cpupower: update the cpu_power according to cpu load

This driver updates the capacity of each core according to current
sched_mc level and cpu frequency (in fact current cpu load)

When the lowest frequencies are used, we are in a light load use case
and we increase the cpu capacity to keep these light tasks on CPU0

sched: use cpu capacity to decide if a ILB is needed
performance: Turn CPUs online while active

Since we don't have separate active hotplugging logic aside the in-governor one in pegasusq, switching to performance governor will always just remain with whatever cores were online before the switch. This activates all available cores on governor start, and turns additional cores off when stopped.
