In the past few years, we have received several reports about SPI
Flash not working properly. This is caused by excessively fast
clock frequency. It's really annoying to fix them one by one. Let's
reduce these aggressive frequencies to 50 MHz. This is a safe and
suggested value in the vendor SDK.

This commit:
1. Removes deprecated "label" property from the dts leds subnnodes;
2. Updates buttons and leds dts description according to kernel docs
examples.
Scope: devices well known to me.
Run-tested: TP-Link ec330-g5u, WiFire S1500.nbn

This commit adds support for following wireless routers:
- Rostelecom RT-FL-1 (Serсomm RT-FL-1)
- Rostelecom S1010 (Serсomm S1010.RT)
The devices are almost identical and the only difference is one bit in the
factory image PID (thanks to Maximilian Weinmann <x1@disroot.org>
(@MaxS0niX) for the info and idea to make one PR for two devices at once).
Devices specification
---------------------
SoC: MediaTek MT7620A, MIPS
RAM: 64 MB
Flash: 16 MB SPI NOR
Wireless 2.4: MT7620 (b/g/n, 2x2)
Wireless 5: MT7612EN (a/n/ac, 2x2)
Ethernet: 5xFE (WAN, LAN1-4)
BootLoader: U-Boot
Buttons: 2 (wps, reset)
LEDs: 1 amber and 1 green status GPIO leds
5 green ethernet GPIO leds
1 green GPIO 2.4 GHz WLAN led
1 green PHY 5 GHz WLAN led
1 green unmanaged power led
USB ports: No
Power: 12 VDC, 1 A
Connector: Barrel
OEM easy installation
---------------------
1. Remove all dots from the factory image filename (except the dot
before file extension)
2. Upload and update the firmware via the original web interface
3. Wait until green status led stops blinking (can take several minutes)
4. Login to OpenWrt initramsfs. It's recommended to make a backup of the
mtd partitions at this point.
4. Perform sysupgrade using the following command (or use Luci):
sysupgrade -n sysupgrade.bin
5. Wait until green status les stops blinking (can take several minutes)
6. Mission acomplished
Return to Stock
---------------
Option 1. Restore firmware Slot1 from a backup (firmware2.bin):
cd /tmp
mtd -e Firmware2 write firmware2.bin Firmware2
printf 1 | dd bs=1 seek=$((0x18007)) count=1 of=/dev/mtdblock2
reboot
Option 2. Decrypt, ungzip and split stock firmware image into the parts,
take Slot1 parts (kernel2.bin, rootfs2.bin) and write them:
cd /tmp
mtd -e Kernel2 write kernel2.bin Kernel2
mtd -e RootFS2 write rootfs2.bin RootFS2
printf 1 | dd bs=1 seek=$((0x18007)) count=1 of=/dev/mtdblock2
reboot

Debricking
----------
Use sercomm-recovery tool. You can use "ALL" mtd partition backup as a
recovery image.
