Update extcon for 4.11

Detailed description for this pull request:
1. Add the new extcon driver.
- Intel INT3496 ACPI USB id detection driver detects whether
  EXTCON_USB_HOST is attached or detached. (extcon-intel-int3496.c)

2. Add the new type of external connector.
- EXTCON_CHG_USB_PD (USB Power Delivery) provides the increased
  power more than 7.5W to device with larger power demand.

3. Add the description for EXTCON_CHG_USB_(SDP|ACA|SLOW|FAST)
- EXTCON_CHG_USB_SDP should always appear together with EXTCON_USB
- EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST.
- EXTCON_CHG_USB_SLOW can provide at least 500mA of current at 5V
- EXTCON_CHG_USB_FAST can provide at least 1A of current at 5V.

4. Modify the connector name of EXTCON_USB_HOST
- "USB_HOST" -> "USB-HOST"

5. Update the extcon core
- Move the private extcon structure into driver/extcon directory.
  The 'struct extcon_dev' should be only handled by extcon core
  to prevent the direct access and to maintain the integrity of it.
- Remove the ambigous operation of extcon_register_notifier()
  in case of the 'extcon_dev' instance is NULL. The user of
  extcon_register_notifier() have to specify the correct instance
  of the provider extcon driver.

6. Update the extcon drivers and fix the minor issues
- Update the extcon-axp288 driver to remove the unncessary code.
- Add pinctrl operation during suspend mode to extcon-usb-gpio driver.
- Clean up the extcon-arizona/adc-jack driver.
- Use the dev_dbg() for debug messsage on extcon-palmas driver.
- Return the error code on failure of extcon_sync()
