ARM: topology: set the capacity of each cores for big.LITTLE

This patchset creates an arch_scale_freq_power function for ARM, which is used 
to set the relative capacity of each core of a big.LITTLE system. It also removes
the broken power estimation of x86.

Modification since v1:
 - Add and update explanation about the use of the table and the range of the value 
 - Remove the use of NR_CPUS and use nr_cpu_ids instead
 - Remove broken power estimation of x86

Peter Zijlstra (1):
  sched, x86: Remove broken power estimation

Vincent Guittot (4):
  ARM: topology: Add arch_scale_freq_power function
  ARM: topology: factorize the update of sibling masks
  ARM: topology: Update cpu_power according to DT information
  sched: cpu_power: enable ARCH_POWER
