Merge branches 'pm-sleep' and 'pm-cpufreq'

* pm-sleep:
  PM / sleep: fix freeze_ops NULL pointer dereferences
  PM / sleep: Fix request_firmware() error at resume

* pm-cpufreq:
  cpufreq: make table sentinel macros unsigned to match use
  cpufreq: move policy kobj to policy->cpu at resume
  cpufreq: cpu0: OPPs can be populated at runtime
  cpufreq: kirkwood: Reinstate cpufreq driver for ARCH_KIRKWOOD
  cpufreq: imx6q: Select PM_OPP
  cpufreq: sa1110: set memory type for h3600

under node /cpus/cpu@0.
Required properties:
- operating-points: Refer to Documentation/devicetree/bindings/power/opp.txt
for details
- None
Optional properties:
- operating-points: Refer to Documentation/devicetree/bindings/power/opp.txt for
details. OPPs *must* be supplied either via DT, i.e. this property, or
populated at runtime.
- clock-latency: Specify the possible maximum transition latency for clock,
in unit of nanoseconds.
- voltage-tolerance: Specify the CPU voltage tolerance in percentage.
