Update extcon for v3.19

This patchset fix minor issue of extcon driver.

Detailed description for patchset:
- Fix typo and change jig cable name of extcon-max77693.c
- Update the extcon_get_edev_by_phandle() because previous extcon_get_edev_by_phandle()
  considered the platform device driver. So, this modification supports
  OF-based extcon lookup method by using the list of extcon devices.
