mb/google/nissa/var/teliks: Adjust usb2 pin of wlan
Since the voltage value measured by the USB2 pin of the wlan is 500mv, it does not meet the design requirements. Adjusting the port length can reduce the voltage to 450mv, which meets the expected settings.
BUG=b:361037189 TEST=1. The voltage measurements are as expected. 2. The Bluetooth and WiFi functions of the wlan module are verified to be normal.
