Update extcon for 3.12

This patchset add new file for OF helper API and modify small fix of extcon-palmas
driver. Also, extcon core dirver use power_efficient_wq instead of system_wq.

Detailed description for patchset:
1. Add new file for OF helper API
- Add OF(OpenFirmware) Helper API which is of_extcon_get_extcon_device().
  This helper API get the extcon device name on extcon consumer device.
- Add usase case about OF helper API of extcon in dwc3-omap.c. dwc3-omap driver
  use extcon subsystem to detect the state of USB/USB-Host cable so dwc3-omap
  call of_extcon_get_extcon_device() to need extcon device name.

2. Modify extcon-palmas.c driver
- Provide option to select whether interrupt is used or not
- Support suspend/resume for palmas driver
- Update palmas interrupt register to detect ID pin
- Code clean to remove unused data
- Rename filename for device tree binding (extcon-twl.txt -> extcon-palmas.txt)

3. Use power_effcient_wq on extcon core driver/extcon-arizona instead of system_wq
- extcon core driver(extcon-gpio.c/extcon-adc-jack.c) use power_effcient_wq
instead of system_wq.

Required Properties:

 - compatible : Should be "ti,palmas-usb" or "ti,twl6035-usb"

 - vbus-supply : phandle to the regulator device tree node.



Optional Properties:

 - ti,wakeup : To enable the wakeup comparator in probe

 - ti,enable-id-detection: Perform ID detection.

 - ti,enable-vbus-detection: Perform VBUS detection.
