Update extcon for 4.6 

Detailed description for patchset:
 1. Add new EXTCON_CHG_USB_SDP type
 - SDP (Standard Downstream Port) USB Charging Port
   means the charging connector.a
 
 2. Add the VBUS detection by using GPIO on extcon-palmas
 - Beaglex15 board uses the extcon-palmas driver
   But, beaglex15 board need the GPIO support for VBUS
   detection.
 
 3. Fix the minor issue of extcon drivers
