ramips: add support for RAISECOM MSG1500 Z.00 (#8385)

Hardware:
  SoC: MediaTek MT7621AT
  Flash: SPI NOR 16MB
  RAM: DDR3 64MB
  2.4GHz: MT7603EN bgn 2x2
  5GHz: MT7612EN nac 2x2
  Ethernet: 1 x WAN and 4 x LAN
  USB: 1 x 3.0
  Button: Reset, WPS

Note: the flash memory capacity is only 64MB.
      You may need to uncheck some options to ensure normal startup.
