The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.
In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.
Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

For mt7621, console is set up via DTS bootargs individually in
device DTS/DTSI files. However, 44 of 74 statements use the
following setting:
chosen {
bootargs = "console=ttyS0,57600";
};
Therefore, don't repeat ourselves and move that definition to the SoC
DTSI file to serve as a default value.
This patch is cosmetic.

For a long time the mt7621 uses a fixed cpu clock which causes a problem

Add the ranges property to the PCI bridges where missing. Add the unit
address to PCI bridge where missing.
Rework the complete rt3883 pci node. Drop the PCI unit nodes from the
dtsi. They are not used by any dts file and should be rather in the dts
than in the SoC dtsi. Express the PCI-PCI bridge in a clean devicetree
syntax. The ralink,pci-slot isn't used by any driver, drop it. Move the
pci interrupt controller out of the pci node. It doesn't share the same
reg and therefore should be an independent/SoC child node.
Move the pci related rt3883 pinctrl setting to the dtsi instead of
defining the very same for each rt3883 board.
If the device_type property is used for PCI units, the unit is treated
as pci bridge which it isn't. Drop it for PCI units.
Reference pci-bridges or the pci node defined in the dtsi instead of
recreating the whole node hierarchy. It allows to change the referenced
node in the dtsi without the need to touch all dts.
Fix the PCI(e) wireless unit addresses. All our PCI(e) wireless chips

As the Interrupts for the PCI adapters are listed in
devicetree we shouldn't need to have them explicit in the code.
The simplest way to do this is to use of_irq_parse_and_map_pci()
and specify an interrupt-map which identifies the different
PCI hosts by bus/slot numbers.
This has the advantage that the hwirq number are mapped to virq
numbers for us, so the ugly hack can go.

This commit makes the following modifications to ramips dts files:
1. Add clkctrl node to all dtsi files (although not used for now)
2. Add clocks and clock-names properties to some nodes (usbphy, pci)
3. Add usbphy node for rt3050 (although not used for now)
4. Add clock-frequency to uart nodes in mt7621.dtsi and mt7628an.dtsi
These modifications, although not fully used at the moment, will make
it easier for FreeBSD to adopt and use LEDE ramips dts files with
minimal changes for easier maintenance.
