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()

Intel INT3496 ACPI device extcon driver documentation

-----------------------------------------------------



The Intel INT3496 ACPI device extcon driver is a driver for ACPI

devices with an acpi-id of INT3496, such as found for example on

Intel Baytrail and Cherrytrail tablets.



This ACPI device describes how the OS can read the id-pin of the devices'

USB-otg port, as well as how it optionally can enable Vbus output on the

otg port and how it can optionally control the muxing of the data pins

between an USB host and an USB peripheral controller.



The ACPI devices exposes this functionality by returning an array with up

to 3 gpio descriptors from its ACPI _CRS (Current Resource Settings) call:



Index 0: The input gpio for the id-pin, this is always present and valid

Index 1: The output gpio for enabling Vbus output from the device to the otg

         port, write 1 to enable the Vbus output (this gpio descriptor may

         be absent or invalid)

Index 2: The output gpio for muxing of the data pins between the USB host and

         the USB peripheral controller, write 1 to mux to the peripheral

         controller
