72bd92bea0 ath79: drop num-cs for SPI controller
None of the spi drivers on ath79 uses the num-cs property.

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.

c65c306d33 ath79: add support for Wallys DR531
Wallys DR531 is based on Qualcomm Atheros QCA9531 v2. Support for this
device was first introduced in e767980eb8 (ar71xx target).

Specifications:

- Qualcomm/Atheros QCA9531 v2
- 550/400/200 MHz (CPU/DDR/AHB)
- 2x 10/100 Mbps Ethernet
- 64 MB of RAM (DDR2)
- 8 MB of flash (SPI NOR)
- 2T2R 2.4 GHz Wi-Fi, with external PA (SE2576L), up to 30 dBm
- 2x MMCX connectors (optional IPEX/U.FL)
- mini PCIe connector (PCIe/USB buses and mini SIM slot)
- 7x LED, 1x button, 1x optional buzzer
- UART, JTAG and LED headers on PCB

Flash instruction (do it under U-Boot, using UART):

  tftpb 0x80060000 openwrt-ath79-...-dr531-squashfs-sysupgrade.bin
  erase 0x9f050000 +$filesize
  cp.b $fileaddr 0x9f050000 $filesize
  setenv bootcmd "bootm 0x9f050000"
  saveenv && reset
