A 4 patch set from Dominik Brodowski, tested and fixed up by rmk
for ARM.

(1)

- the system3.c cpufreq notifier couldn't possibly compile before because
      cpufreq_updateminmax has been undefined for ages.
- clean up sa1100fb.c notifier to specify exactly what's left TBD.
- double #include of cpufreq.c in drivers/pcmcia/sa1100_generic.c

(2)

Split up config symbols, add help text for CPU_FREQ_PROC_INTF

(3)

- update the Integrator CPUfreq driver so that it can get along with
  cpufreq policies.
- modularize Integrator CPUfreq driver (all it did with
  !CONFIG_CPU_FREQ was to print out some debug information)

(4)

- update the SA11x0 CPUfreq drivers so that they can get along with
  cpufreq policies and governors.
- update the cpufreq core so that cpufreq_get() returns something
  sensible during the first ->setpolicy or ->target call.
