The following commits break cpuidle on SH-Mobile ARM:

46bcfad7 cpuidle: Single/Global registration of idle states
e978aa7d cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state

This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.

It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".

This patch adds a shared SH-Mobile ARM specific CPUIdle
implementation supporting WFI only at this point. It
serves as a common point for late registration of the
arch-specific CPUIdle code, and supports adding extra
sleep modes using the callback shmobile_cpuidle_setup()
together with shmobile_cpuidle_modes[].
