In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.
The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi
While this is a cosmetic change, backporting it to 19.07 will be a
major help for anyone doing backports of device support. Without it,
every backporter would have to remember to manually add the chosen node
to the device's DTS.

TP-Link Archer D50 v1 is a dual-band AC1200 router + modem.
The router section is based on Qualcomm/Atheros QCA9531 + QCA9882.
The "DSL" section is based on BCM6318 but it's currently not supported.
Internally eth0 is connected to the Broadcom CPU.
Router section - Specification:
CPU: QCA9531 650/600/200 MHz (CPU/DDR/AHB)
RAM: 64 MB (DDR2)
Flash: 8 MB (SPI NOR)
Wifi 2.4GHz: QCA9531 2T2R
Wifi 5GHz: QCA9982 2T2R
4x 10/100 Mbps Ethernet
8x LED, 3x button
UART header on PCB
Known issues:
DSL not working (eth0) (WIP)
UART connection

The following instructions require a connection to the J2 UART header.
Flash instruction under U-Boot, using UART
------------------------------------------
1. Press any key to stop autobooting and obtain U-Boot CLI access.
2. Setup ip addresses for U-Boot and your tftp server.
3. Issue below commands:
tftpboot 0x81000000 openwrt-ath79-generic-tplink_archer-d50-v1-squashfs-sysupgrade.bin
erase 0x9f020000 +$filesize
cp.b 0x81000000 0x9f020000 $filesize
reset
Initramfs instruction under U-Boot for testing, using UART
----------------------------------------------------------
1. Press any key to stop autobooting and obtain U-Boot CLI access.
2. Setup ip addresses for U-Boot and your tftp server.
3. Issue below commands:
tftpboot 0x81000000 openwrt-ath79-generic-tplink_archer-d50-v1-initramfs-kernel.bin
bootm 0x81000000
Restore the original firmware
-----------------------------
0. Backup every partition using the OpenWrt web interface
1. Download the OEM firmware from the TP-Link website
2. Extract the bin file in a folder (eg. Archer_D50v1_0.8.0_1.3_up_boot(170223)_full_2017-02-24_09.37.45.bin)
3. Remove the U-Boot and the Broadcom image part from the file.
Issue the following command:
dd if="Archer_D50v1_0.8.0_1.3_up_boot(170223)_full_2017-02-24_09.37.45.bin" of="Archer_D50v1_0.8.0_1.3_up_boot(170223)_full_2017-02-24_09.37.45.bin.mod" skip=257 bs=512 count=15616
4. Double check the .mod file size. It must be 7995392 bytes.
5. Flash it using the OpenWrt web interface. Force the update if needed.
WARNING: Remember to NOT keep settings.
5b. (Alternative to 5.) Flash it using the U-Boot and UART connection.
Issue below commands in the U-Boot:
tftpboot 0x81000000 Archer_D50v1_0.8.0_1.3_up_boot(170223)_full_2017-02-24_09.37.45.bin.mod
erase 0x9f020000 +$filesize
cp.b 0x81000000 0x9f020000 $filesize
reset
