  Log:
  Fix the check for acpi_perf(4) so that we verify if it is fully attached
  or just offering info.  In the former case, we don't probe/attach to allow
  the ACPI driver precedence.  A refinement of this would be to actually
  use the info provided by acpi_perf(4) to get the real CPU clock rates
  instead of estimating them but since all systems that support both
  acpi_perf(4) and ichss(4) export the control registers to acpi_perf(4),
  it can just handle the registers on its own.
