c61d4eeedb ath79: fix RS-485 on Teltonika RUT-955
DTR GPIO isn't actually needed and triggers boot warning.
TX pin was off by one (GPIO 19 instead of GPIO 18).

7054721cf9 ath79: enable UART in SoC DTSI files
The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.

Where the majority of devices is using it, also move the serial0
alias to the DTSI.

*) Since GL-USB150 even defines serial0 alias, the missing uart
   is probably just a mistake. Anyway, disable it for now so this
   patch stays cosmetic.

Apply this to 21.02 as well to remove an unnecessary backporting
pitfall.

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.

c8b309b53d ath79: split Teltonika RUT955 to support other RUT9xx models
Split device-tree of Teltonika RUT955 into a generic RUT9xx part and
a part specific to that version of RUT955 already supported.
Also harmonize GPIO and LED names with what is used by the vendor
firmware and assign RS485 DTR signal.
