ramips: Add support for Phicomm PSG1208

This patch adds support for Phicomm PSG1208.This is a router with MT7620A SoC with 8M flash and 64M ram.
The WPS led is uesd as status_led because the power light can't be controlled with GPIO.
It seems that the 5g wifi led is connected to MT7612E and it can't be controlled with GPIO too.
