This adds the cpus node to the Integrator/AP device tree so
that we have a proper placeholder to put in the DT-defined
operating points for the generic DT/OPP cpufreq driver,
along with the proper operating points.
The old Integrator cpufreq driver would resolve the max
frequency to 71MHz, and the min frequency to 12 MHz, but
the clock driver can actually handle any frequency inbetween
so I picked a few select frequencies as OPPs. The cpufreq
framework doesn't seem to deal with sliding frequency scales,
only fixed points so 7 OPPs is better than 2 atleast.
We define a CPU node since this is required for cpufreq-dt,
however we do not define any compatible string for the CPU
since this architecture has pluggable CPU modules and we
do not know which one will be used. If necessary, the CPU
compatible can be filled in by the boot loader, but for
just cpufreq-dt it is not required.

This adds the cpus node to the Integrator/CP device tree so
that we have a proper placeholder to put in the DT-defined
operating points for the generic DT/OPP cpufreq driver,
along with two working operating points.
I have only put in 48 and 50 MHz because going to e.g. 36
MHz hangs the system when CLCD graphics are active.
Presumably the memory bus gets to slow to feed the display
and the systems hangs for this reason. The ideal solution
would be for the display controller to put constraints on
the memory bus frequency, but that need to be a separate
longer-term project.

32bit devicetree changes for Rockchip including removal of skeleton.dtsi
inclusion, missing unit names for memory nodes, various frequency
optimizations allowing for better performance on rk3066, the usage of
pin constants to bridge between the two numbering schemes used (gpio
controllers using 0-31 and pins being labeled A0-A7,..., D0-D7)
and UHS/HS modes for the mmc controllers on the popmetal board.

Lots of platforms contain clocks which if turned off would prove fatal.
The only way to recover is to restart the board(s). This driver takes
references to clocks which are required to be always-on. The Common
Clk Framework will then take references to them. This way they will
not be turned off during the clk_disabled_unused() procedure.
In this patch we are identifying clocks, which if gated would render
the STiH407 development board unserviceable.

I notice some mistakes in the SoC DTSI; wrong interrupts properties
of timer nodes, mismatch between the node name and the compatible
for sdctrl block. Given those problems fixed, the common parts
among SoCs are less than I had first expected. The more and more
property overrides are making the SoC DTSI unreadable.
Stretch out the SoC DTSI files and fix the following:
- Fix the 3rd cell of the interrupts property of the timer nodes
for Pro4, Pro5, PXs2
- Fix the node name mioctrl to sdctrl for Pro5, PXs2
- Fix the second region of l2 node for PXs2

(to @0) to boost performances. A DMA translation through "dma-ranges"
property was needed for other masters than the M4 CPU.
stm32f429-disco doesn't use remapping so doesn't need this DMA translation.
