7b9a0c264c ath79: use dynamic partitioning for TP-Link CPE series
CPExxx and WBSxxx boards with AR9344 SOC
use the OKLI lzma kernel loader
with the offset of 3 blocks of length 4k (0x3000)
in order to have a fake "kernel" that cannot grow larger
than how it is defined in the now static OEM partition table.

Before recent changes to the mtdsplit driver,
the uImage parser for OKLI only supported images
that started exactly on an eraseblock boundary.

The mtdsplit parser for uImage now supports identifying images
with any magic number value
and at any offset from the eraseblock boundary
using DTS properties to define those values.

So, it is no longer necessary to use fixed sizes
for kernel and rootfs

3a4b751110 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.

f330f991c1 ath79: enable LNA for all ar9344 TPLink CPE devices
The TPLink CPE devices CPE210/CPE510 based on ar9344 have a build-in
Low Noise Amplifier on both of the 2x2 mimo rx chains.
This patch activates those two LNAs in the respective receiving chains
and hence improves the RX sensitivity by about 20dB.

Tested on CPE510 v2 & v3.

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.

a99614a44f ath79: consistently use "info" label for default-mac partition
The tp-link safeloader devices typically contain a partition
"default-mac" which stores the MAC addresses. It is followed by other
partitions containing device info, like

  {"default-mac", 0x610000, 0x00020},
  {"pin", 0x610100, 0x00020},
  {"product-info", 0x611100, 0x01000},

In DTS, we typically assign a 0x10000 sized partition for these,
which is mostly labelled "mac" or "info". In rarer cases, the
partitions have been enclosed in a larger "tplink" or "config"
partition.

However, when comparing different devices, the implementation appears
relatively arbitrary at the moment.
Thus, this PR aims at harmonizing these partitions by always using
the name "info" for the DTS partition containing "default-mac".
"info" is preferred over "mac" as we never just have "default-mac"
alone, but always some other device-info partitions as well.

While at it, this also establishes a similar partitioning for the
few devices where the "info" partitions are part of a bigger
unspecific "config" partition or similar.

Besides the harmonization itself, this also allows to merge a few
cases in 11-ath10k-caldata.

d7fb7ac278 ath79: increase kernel partition for ar9344 TP-Link CPE/WBS
The kernel has become too big again for the ar9344-based TP-Link
CPE/WBS devices which still have no firmware-partition splitter.

Current buildbots produce a kernel size of about 2469 kiB, while
the partition is only 2048 kiB (0x200000). Therefore, increase it
to 0x300000 to provide enough room for this and, hopefully, the
next kernel.

231dc26867 treewide: remove dts-v1 identifier from DTSI files
The "/dts-v1/;" identifier is supposed to be put once at the beginning
of a device tree file. Thus, it makes no sense to provide it a second
time in to-be-included DTSI files.

This removes the identifier from all DTSI files in /target/linux.

Most of the DTS files in OpenWrt do contain the "/dts-v1/;". It is
missing for most of the following targets, though:
mvebu, ipq806x, mpc85xx, ipq40xx

This does not touch ipq806x for now, as the bump to 4.19 is close.

226bc91109 ath79: improve TP-Link CPE DTSI names for ar9344 SOC
The initial DTSI names for the TP-Link CPE devices have become
quite confusing, as several non-V1 devices now use the *-v1.dtsi,
the *cpe510-v1.dts does not use the cpe510.dtsi, etc.

This introduces a new naming scheme based on whether devices have
one or two ports, which should be easier to grasp.
