ARM: multi_v7_defconfig: enable Rockchip io-domain driver

The io-domain driver is necessary to notify the soc about voltages changes happening on supplying regulators. Probably the most important user right now is the mmc tuning code, where the soc needs to get notified when the voltage is dropped to the 1.8V point.

As this option is necessary to sucessfully tune UHS cards etc, it should get built in.

---
When booting a Veyron-Jerry from an sd-card it got stuck, as the tuning failed due to the missing voltage notification and the mmc completely fails initialization of the card, if this happens.
With this option enabled, I could again boot from my sd-card.

This is based on the

This enables the newly added hardware crypto module found for example on the rk3288.

2.6.4

The rk808 supplies two clock outputs with one going back into the soc as 32kHz supply, supplying some core soc clocks with it. The system can boot without it being present, but it is needed for example as source clock for the thermal driver.

Looks cut off :)

Anyway, applied 1-3.

I only wanted to say that this is based on the latest multi_v7 from the armsoc/defconfig branch, but it looks I forgot to finish that sentence ;-)

Thanks
