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.

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.

6e7f40dff3 ath79: routerboard-92x: ensure explicit bios size in DTSI
The missing "size" property was acceptable in the context of a single
DTS as the underlying device is known to have a 64KB flash, and thus
the bios partition fit exactly between the preceding and following ones.

However as this block has moved in a DTSI, for the sake of clarity and
explicitness the size property is added to ensure that if the flash
happens to be larger than expected, the bios partition remains properly
sized.

b2e1f7101d ath79: add support for MikroTik RouterBOARD 921GS-5HPacD-15s
The MikroTik RouterBOARD 921GS-5HPacD-15s (mANTBox 15s) is an outdoor
antenna for 5 GHz with an built-in router. This ports the board from
ar71xx.

See https://mikrotik.com/product/RB921GS-5HPacD-15S for more info.

Specifications:
 - SoC: Qualcomm Atheros QCA9558 (720 MHz)
 - RAM: 128 MB
 - Storage: 128 MB NAND
 - Wireless: external QCA9892 802.11a/ac 2x2:2
 - Ethernet: 1x 1000/100/10 Mbps, integrated, via AR8031 PHY, passive PoE in
 - SFP: 1x host

Working:
 - NAND storage detection
 - Ethernet
 - Wireless
 - 1x user LED (blinks during boot, sysupgrade)
 - Reset button
 - Sysupgrade

Untested:
 - SFP cage (probably not working)

Installation (untested):
 - Boot initramfs image via TFTP and then flash sysupgrade image

As the embedded RB921-pcb is a stripped down version of the RB922 this patch
adds a common dtsi for this series and includes this to the final dts-files.
