Subject: ramips: add support for STORYLiNK SAP-G3200U3

STORYLiNK SAP-G3200U3 is an AC1200 router based on MT7621AT+MT7602EN+MT7612EN.
It has 128MB DDR3, 8MB NOR FLASH, 5-port Gbps switch and 1x USB 3.0.

The following patch adds support for this device.

Tested and working:
* ethernet
* both WiFi radios
* USB 3.0
* buttons
* ethernet switch and USB diag LEDs
* UART
* GPIOs

Tested and not working:
* LEDs for WiFi radios (connected with WiFi chips, not supported in mt76?)
* failsafe mode (known problem, needs workaround like other MTK based devices)
