  Log:
  Add the acpi_get_features() method.  This method is called on child drivers
  to see what features they may support before calling identify/probe/attach.
  This is necessary because the ACPI 3.0 spec requires driver support be
  advertised before running any methods.  For now, the flags are as specified
  in for the _PDC and _OSC methods but we can support private flags as needed.
  
  Add an implementation of this for acpi_cpu.  It checks all its children
  (notably cpufreq drivers) and calls the _PDC method to report the results.
