ramips: mt76x8: add support for Keenetic KN-1510

Specification:
* CPU: MediaTek MT7628AN (580 MHz)
* Flash: GigaDevice GD25Q128CSIG (16 MiB)
* RAM: Winbond W9751G6KB-25 (64 MiB)

WikiDevi page: <https://wikidevi.wi-cat.ru/Keenetic_City_(KN-1510)>

How to flash:
* Configure TFTP server with IP address 192.168.1.2/24
* Serve OpenWrt factory image as "KN-1510_recovery.bin"
* Connect the PC to router's LAN port, hold the reset button and power
  the router up. When the power LED starts blinking release the
  button.

The same instructions apply to OEM firmware, except one can take it
from osvault.keenetic.net
