A recent series has added CPU numbers to a lot of dts files,
but unfortunately in a few cases the #address-cells
and #size-cells values are missing, which causes build warnings.
This adds the missing ones for sunxi and sama5 that I found
through build testing.

We need three steps to prepare for the new Armadillo reference DT board code:
 - Split the device list into r8a7740_early_devices used by the old platform
   data setup (board-armadillo.c) and r8a7740_devices_dt used by both
   setup variants.
 - Introduce new r8a7740_init_delay() to be more flexible about calling
   shmobile_setup_delay().
 - For the generic r8a7740 support, we switch to device tree setup for
   the GIC, the irqpin devices and the I2C controllers.

This is slightly similar to commit 3b00f934

The Kirkwood CPU Freq driver needs a CPU definition in order for the probe
routine to activate it. Add a suitable definition to kirkwood.dtsi

This definition is only correct for single core SoCs. There is a dual core
SoC in the kirkwood family (88F632X) but the rest of the Kirkwood drivers in
the kernel don't currently support it. If they ever do the cpus definition
would need to be duplicated in each of the SoC specific include files.

The clocksource API has changed slightly, which causes a harmless
warning:

/git/arm-soc/drivers/clocksource/nomadik-mtu.c:259:28: warning: 'nmdk_timer_match' defined but not used [-Wunused-variable]
 static struct of_device_id nmdk_timer_match[] __initconst = {

while removing the warning.

Some kirkwood variants (for instance present in the prestera SoCs) do
not have all the peripherals whose nodes are declared in
kirkwood.dtsi. These missing peripherals are SATA, SDIO, and RTC.

As discussed in [1], to avoid that these missing peripherals get
initialized which could result in system hangs when accessing
undocumented/not present HW registers, their corresponding OF nodes
should not get declared at all for some kirkwood variants.

The corresponding OF nodes of these peripherals thus are moved from
kirkwood.dtsi to the kirkwood-628x.dtsi files so that they still are
initialized for these variants where they are present.

Instead of having one separate pinmux configuration for each LED, for

yet another side.

When the pinmux mechanism was added in Kirkwood, the device driver
core was not yet providing the possibility of attaching pinmux
configurations to all devices, drivers had to do it explicitly, and
not all drivers were doing this.

Now that the driver core does that in a generic way, it makes sense to
attach the pinmux configuration to their corresponding devices.

This allows the pinctrl subsystem to show in debugfs to which device
is related which pins, for example:
