ARM: dts: msm: Add VBUS/ID configuration for USB secondary port on Lahaina 

This change adds GPIO configuration for USB VBUS/ID detection and
enabling 5v vbus in host mode. It adds extcon_usb2 device node for
using this configuration through USB extcon gpio driver for
notifying vbus/ID status on connecting USB cable.
