This series adds support for clock and reset (and MFD to populate them)
for UniPhier SoCs.

On UniPhier SoCs, one system control block contains various registers
for clock, reset, and others in it.

I consulted Arnd for better implementation for clock/reset drivers in such a case.
https://lkml.org/lkml/2016/4/18/605

After a while, I chose MFD approach and found it is a good fit in my case.

So, here I intentionally included clock, reset, MFD in one patch series
because they are related with one another.

I have not completed this series.  Some known problems are:
 - Binding document is missing
 - I need to fill clock/reset tables a bit more.

Please do not apply this series.

But, this sereis should be enough for reviewing
if my basic approach is OK or not.

Your feedback is appreciated.
