qualcommax: add missing WAN LED support to Spectrum SAX1V1K routers

Fixed an issue where both WAN LEDs light up before plugging in the
ethernet cable and no blinking regardless of WAN network activity.

Updated the LED configuration to reflect proper status:
Green indicates 2.5Gb connection speed.
Yellow indicates other connection speed and traffic activity.

This resolves inconsistent WAN LED behavior on Spectrum SAX1V1K routers.
