Changes since v13:
- Return values for idle states propagated back to the cpuidle driver.
- Remove static bool cpuidle_drv_init.
- Register cpuidle driver and cpuidle device separately.
- cpuidle device registered only when the SPM for the cpu is probed.
- Initialization changes to ensure dynamic cpuidle devices are registered only after the cpuidle driver is registered.
- Removed wmb, replaced with a poll loop to ensure that the SPM registers are written before executing wfi.
- Added spm_register_write_sync() for write guarantees.
- Removed irrelevant return value for spm_set_low_power_mode().
- Added comments, updated module description.
- Removed Reviewed-by and Acked-by on the spm and cpuidle-qcom patches.

I think this series should also include updates to qcom_defconfig that enable QCOM_PM and the cpuidle driver.

Then it will be enabled by default and get more broad testing.
