Update extcon for 4.4

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.
