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.

The clock definitions get a lot shorter due to the soc clocks being handled by
rk3188-cru and only the input clock remains. These can now simply live
in the main rk3xxx.dtsi without affecting readability.

At the same time, rename the node to oscillator, adding a clock-output-names
property to match how the rk3288 handles this.

This adds a node for the clock and reset unit on rk3188 and rk3066 SoCs and
also updates the device nodes retrieve their clocks from there, instead of
the previous gate clock nodes.

Introduce the grf syscon and convert the pinctrl drivers for rk3066 and rk3188
to use it, instead of mapping the grf registers themselfs.

The pmu is needed to bring up the cores during smp operations and later
also other system parts. Therefore add a node and documentation for it.

This adds the device-node and config select to enable the
scu in all Rockchip Cortex-A9 SoCs.

RK2928 and RK3066 contain a dw_apb timer component, while the rk3188 uses
a slightly similar but still different timer component. But all of them
support the ARM-global-timer that got added as clocksource driver recently.

So enable support for it to get a working clocksource for rk3188.

The rk3188 SoC shares a lot of peripherals with the rk3066 SoC,
but not all. Therefore move the common parts to a shared dtsi.
