Update extcon for 4.14

Detailed description for this pull request:
1. Add new 'extcon-usbc-cros-ec.c' driver
- ChromeOS Embedded Controller extcon driver supports
  the detection of the Display Port (EXTCON_DISP_DP)
  through USB C-type and contol it.

2. Update extcon core
- Modify the description for both functions and structures
  in order to improve the readability and give the more correct
  guide about the role of functions because there are different
  explanation even if the same arguments.

- Keep the indentation with tab instead of space

- Remove the following deprecated extcon API. The deprecated API
  are exchanged on all of linux tree.
  : extcon_get_cable_state_() -> extcon_get_state()
  : extcon_set_cable_state_() -> extcon_set_state_sync()

3. Include the two immutable branch as following:
- ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver
  because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory.
- ib-extcon-usb-phy-4.14 for removing the deprecated extcon API
  because the usb/phy driver usese the deprecated extcon API.
  So, this immutable branch alters the extcon API and then
  remove them from extcon.

4. Fix minor issue of extcon driver
- Fix the MHL detection on extcon-max77693.c
- Convert to using %pOF instead of full_name on extcon.c
- Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c
