Update extcon for v3.17

This patchset add new extcon provider driver and fix minor issue of extcon driver.

Detailed description for patchset:
1. Add new Silicon-Mitus SM5502 MUIC (Micro-USB Interface Controller) device
- extcon-sm5502 driver  is capable of identifying the type of the external power
source and attached accessory. And external power sources, such as Dedicated
charger or a standard USB port, are able to charge the battery in the smart
phone via the connector.

2. Fix minor issue of extcon driver
- extcon-arizona driver
- extcon-palmas driver
- Remove unnecessary OOM messages for all extcon device drivers

3. Fix minor issue of extcon core
- Re-order the sequence of extcon device driver in Kconfig/Makefile alphabitically
- Set parent device of extcon device automatically using devm_extcon_dev_allocate()

4. Fix MAX77693 driver
- This patchset has dependency on MFD/Regulator/Extcon. So, Lee Jones
(MFD Maintainer) created Immutable branch between MFD and Extcon due
for v3.17 merge-window and then I merged this patchset from MFD git repo[1]
to Extcon git repo.
