This patch uses the SOC variable to calculate DTS names automatically
based on the SOC and the device definition node name.
This reduces redundancy and (by having to choose DTS name
appropriately) will unify the naming of a device in different places
(image/Makefile, DTS name, compatible, image name). This is supposed
to make life easier for developers and reviewers.
Since the kernel uses a "soc-device.dts" scheme for this target, we
use this for the derivation of DEVICE_DTS, too, and rename the files
not having followed it so far.
Note that for some devices the kernel itself is inconsistent, leaving
us with a manual overwrite for ap.dk01.1-c1 and ap.dk04.1-c1.

- replace licence texts with SPDX-License-Identifier where
applicable.
- make node-names more generic to fit with Device-Tree Release v0.2
Section 2.2.2 Generic Names Recommendation.
- utilize wifi0/1, blsp1_uart1 labels

The BDFs for all boards were upstreamed to the ath10k-firmware
repository and are now part of ath10k-firmware 2018-04-19.

The tz and smem reserved-memory information handled in the upstream Linux
sources by the SoC specific dtsi and not by the the boards dts. Using the
same approach in OpenWrt avoids unneccessary duplication.

The reserved-memory regions are mostly undocumented by QCA and are named
very unspecific in the QSDK device trees. It was tried to clean them up by
commit 71ed9f10a3 ("ipq40xx: Use detailed reserved memory for A42") and
similar changes.
The features which require these regions were mostly unknown but
Senthilkumar N L <snlakshm@qti.qualcomm.com> and Sricharan Ramabadhran
<srichara@qti.qualcomm.com> provided some more insight in some of them:
* crash dump feature
- a couple of regions used when 'qca,scm_restart_reason' dt node has the
value 'dload_status' not set to 1
+ apps_bl <0x87000000 0x400000>
+ sbl <0x87400000 0x100000>
+ cnss_debug <0x87400000 0x100000>
+ cpu_context_dump <0x87b00000 0x080000>
- required driver not available in Linux
- safe to remove
* QSEE app execution
- region tz_apps <0x87b80000 0x280000>
- required driver not available in Linux
- safe to remove
* communication with TZ/QSEE
- region smem <0x87b80000 0x280000>
- driver changes not yet upstreamed
- must not be removed because any access can crash kernel/program
* trustzone (QSEE) private memory
- region tz <0x87e80000 0x180000>
- must not be removed because any access can crash kernel/program
Removing the unnecessary regions saves some kilobyte of reserved-memory and
cleans up the device tree:
* 2560 KiB
- 8devices Jalapeno
- AVM FRITZ!Box 4040
- Compex WPJ428
- Meraki MR33 Access Point
- OpenMesh A42
* 14336 KiB
- GL.iNet GL-B1300
- Qualcomm Technologies, Inc. IPQ40xx/AP-DK01.1-C1

The AVM Fritz!Box 4040 uses an IPQ4018 as SoC and not an IPQ4019. The DTS
must be adjusted to reflect this.
