This PR adds support for router Beeline Smart Box TURBO+.
OEM/ODM Serсomm. Almost identical to Serсomm S3.

Specification
-------------
SoC Type: MediaTek MT7621AT (880 MHz, 2 cores)
RAM (Nanya NT5CC64M16GP): 128 MiB
Flash (Macronix MX30LF1G18AC): 128 MiB
Wireless 2.4 GHz (MT7603EN): b/g/n, 2x2
Wireless 5 GHz (MT7615N): a/n/ac, 4x4
Ethernet: 5 ports - 5×GbE (WAN, LAN1-4)
USB ports: 1xUSB3.0
Buttons: 2 button (reset, wps)
LEDs: Red, Green, Blue
Zigbee (EFR32MG1B232GG): 3.0
Stock bootloader: U-Boot 1.1.3
Power: 12 VDC, 1.5 A

Installation
------------
Attach serial console, then boot the initramfs image via TFTP.
Once inside OpenWrt, run sysupgrade -n with the sysupgrade file.
