Subject: [PATCH v5 0/2] PM / devfreq: Change the device name on sysfs entry

These patches change the name of sysfs entry for devfreq/devfreq-event device
as following:
- old
For devfreq, /sys/class/devfreq/[non-standard device name]
For devfreq-event, /sys/class/devfreq-event/event.(X)

- new
For devfreq, /sys/class/devfreq/devfreq(X)
For devfreq-event, /sys/class/devfreq-event/event(X)

Changes from v4:
- Applied the patch1/2 on v4 series.
- Add new ABI document for devfreq-event class.

Changes from v3:
(https://lkml.org/lkml/2017/1/16/254)
- Patch3 initializes the init value of 'event_no' in order to remove
  the unneeded operation (-1) when calling the atomic_inc_return(&event_no).
- Patch4 uses the integer type for unique number of devfreq device.

Changes from v2:
(https://lkml.org/lkml/2016/12/28/102)
- On v2 patchset, patch1/2/3/5 were merged on devfreq git repo.
- Remain the warning message for exynos-ppmu.c
  when failed to get the clock of ppmu.
- Rebase these patches on devfreq git repo[1].

Changes from v1:
- Rebase these patches on v4.10-rc1.
- Include the separate patch[2] in these patches.

Depends on:
- These patches are based on patch[1].
