6f96a4d043 ath79: remove model name from LED labels
Currently, we request LED labels in OpenWrt to follow the scheme

  modelname:color:function

However, specifying the modelname at the beginning is actually
entirely useless for the devices we support in OpenWrt. On the
contrary, having this part actually introduces inconvenience in
several aspects:

  - We need to ensure/check consistency with the DTS compatible
  - We have various exceptions where not the model name is used,
    but the vendor name (like tp-link), which is hard to track
    and justify even for core-developers
  - Having model-based components will not allow to share
    identical LED definitions in DTSI files
  - The inconsistency in what's used for the model part complicates
    several scripts, e.g. board.d/01_leds or LED migrations from
    ar71xx where this was even more messy

Apart from our needs, upstream has deprecated the label property
entirely and introduced new properties to specify color and
function properties separately. However, the implementation does
not appear to be ready and probably won't become ready and/or
match our requirements in the foreseeable future.

However, the limitation of generic LEDs to color and function
properties follows the same idea pointed out above. Generic LEDs
will get names like "green:status" or "red:indicator" then, and
if a "devicename" is prepended, it will be the one of an internal
device, like "phy1:amber:status".

With this patch, we move into the same direction, and just drop
the boardname from the LED labels. This allows to consolidate
a few definitions in DTSI files (will be much more on ramips),
and to drop a few migrations compared to ar71xx that just changed
the boardname. But mainly, it will liberate us from a completely
useless subject to take care of for device support review and
maintenance.
To also drop the boardname from existing configurations, a simple
migration routine is added unconditionally.

Although this seems unfamiliar at first look, a quick check in kernel
for the arm/arm64 dts files revealed that while 1033 lines have
labels with three parts *:*:*, still 284 actually use a two-part
labelling *:*, and thus is also acceptable and not even rare there.

41cc7edc15 ath79: move dts-v1 statement to ath79.dtsi
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 ath79, 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 ath79.dtsi file 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 parent
ath79.dtsi, which is (indirectly) included by all DTS files. All
other occurences are removed.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes to make sure the ath79.dtsi or its
descendants are always included first.

0d23fd2ab2 treewide: dts: Remove default-state=off property from all gpio LED nodes
>From the Documentation/devicetree/bindings/leds/common.txt:

- default-state : The initial state of the LED. Valid values are "on", "off",
  and "keep". If the LED is already on or off and the default-state property is
  set the to same value, then no glitch should be produced where the LED
  momentarily turns off (or on). The "keep" setting will keep the LED at
  whatever its current state is, without producing a glitch.  The default is
  off if this property is not present.

So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.
