From: Conor Dooley <conor.dooley@microchip.com>

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.

Thanks for your patch!

Perhaps we should add an rzfive_defconfig?

I dunno, do we want (potentially a bunch of) platform specific
defconfigs? I'd sooner delete the ones that we have than add more!
I would suggest to just turn on NONPORTABLE, but that isn't a solution
given that the RZ/Five support requires turning off Zicbom. Ultimately I
think it is Palmer's decision whether we add a defconfig for the
platform - it is a bit of a special case given the aforementioned
incompatibility.
