Update extcon for v3.15

This patchset fix minor issue.

The extcon-palmas/gpio use SIMPLE_DEV_PM_OPS macro instead of legacy method.
OF helper function of extcon move in extcon core to remove separate of_extcon.c
and change the name of OF helper function as following because previous function
name is complicated and ambiguous naming.
- of_extcon_get_extcon_dev() -> extcon_get_edev_by_phandle()
