During the restructuring of the Rockchip Cortex-A9 dtsi files it seems
like the pinctrl settings vanished at some point from the mmc0 support.

This of course renders them unusable, so readd the necessary pinctrl
properties.

The Curie2 uses a tps659102 as its main pmic, so add the i2c1 and tps65910
node as well as define the used voltages and regulator-names according to
the schematics.

Also fix the supply of the sd0 regulator, as it is supplied by the vio reg.

Use the handles for subsequent changes to nodes, similar to like the rk3288
submission does it.

Comments received from the rk3288 submission indicated that a generic subnode
to group soc components should not be used.

So to keep all rockchip devicetree files similar, remove it from rk3066 and rk3188.

Add the missing 'compatible' property to device tree root node of

 - rk3066a-bqcurie2.dts
 - rk3188-radxarock.dts

and document the new values.
