It's been a while since this was run, and there's a few things that have
changed. Firstly, almost all of the Renesas stuff vanishes because the
config for the RZ/Five is gated behind NONPORTABLE. Several options
(like CONFIG_PM) are removed as they are the default values.

To retain DEFVFREQ_THERMAL and BLK_DEV_THROTTLING, add PM_DEVFREQ and
BLK_CGROUP respectively.
