Update extcon for 4.4

Browse source 
Detailed description for patchset:
 1. Update the extcon core:
 - Modify the unique identification and name of each external connector
   with the additional prefix to clarify both attribute and meaning of
   external connector as following:
 : EXTCON_CHG_* mean the charger connector.
 : EXTCON_JACK_* mean the jack connector.
 : EXTCON_DISP_* mean the display port connector.
 
 - Keep the standard name of USB charging port by refering to the
   "Battery Charging v1.2 Spec and Adopters Agreement"[1] to use
   the standard name of USB charging port as following:
 : EXTCON_CHG_USB_SDP /* Standard Downstream Port */
 : EXTCON_CHG_USB_DCP /* Dedicated Charging Port */
 : EXTCON_CHG_USB_CDP /* Charging Downstream Port */
 : EXTCON_CHG_USB_ACA /* Accessory Charger Adapter */
 [1] www.usb.org/developers/docs/devclass_docs/BCv1.2_070312.zip
 
 2. Update the extcon-arizona.c driver:
 - Support the WM8998 and WM1814 codec for jack detection.
 - Support for the ADC mode microphone detection and the general
   purpose switch for pop suppression.
 - Fix bug include fixing the headphone detection accuracy
   at the top end of the range and some corrections around
   the use of the microphone clamps.
 
 3. Update the extcon-gpio.c driver:
 - Clean-up the extcon-gpio driver and fix minor issue before
   supporting the Device tree binding of it.
 
 4. Clean-up and fix the minor issue for extcon drivers:
 - Export OF module alias information for extcon-rt8973a.c and extcon-sm5502.c.
 - Fix wrong type of variable of for extcon-rt8973a.c and extcon-sm5502.c.
 - Use resource managed API for extcon-axp288.c.
