d0b7e186e6 ramips: mt7621: create DTSI for ELECOM WRC GS devices with 2 PCI
This creates a dedicated DTSI for ELECOM WRC GS devices with 2 PCI
WiFi chips in preparation for the 1 chip - dual radio devices, so
the latter can reuse part of the common definitions.

621297e867 ramips: move dts-v1 statement to top-level DTSI files
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.

95a05b12d7 ramips: provide common definition for ELECOM WRC GS devices
Add a common definition for ELECOM WRC "GS" devices to mt7621.mk
to not repeat the same assignments five times.

To keep the naming consistent, slightly rename the DTSI and the
factory image recipe as well.

Note that elecom_wrc-1167ghbk2-s uses a slightly different build
recipe for the factory image, so we keep it separate.
