extcon: Add support for qcom SPMI PMIC USB id detection hardware (2016-09-13 11:26:26 +0900)

Update extcon for 4.9

Detailed description for this pull request:
1. Support the extcon property and add the synchronization APIs.
- This feature supports the extcon property for external connector
because each external connector might have the property according to
the H/W design.

- The property name should keep the following style.
: EXTCON_PROP_USB_[property_name]
: EXTCON_PROP_CHG_[property_name]
: EXTCON_PROP_JACK_[property_name]
: EXTCON_PROP_DISP_[property_name]

- Add the new extcon APIs to support the extcon property.
: extcon_set_property()
: extcon_get_property()
: extcon_set_property_capability()
: extcon_get_property_capability()

- Add the new synchronization extcon APIs.
: This feature adds the synchronization extcon APIs to support the noti
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.

The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().

: extcon_sync()
: extcon_set_state_sync()
: extcon_set_property_sync()

- Change the name of existing APIs.
: extcon_set_cable_state_() -> extcon_set_cable()
: extcon_get_cable_state_() -> extcon_get_cable()

2. Add the extcon type to group the connector into five category.
- EXTCON_TYPE_USB : USB connector
- EXTCON_TYPE_CHG : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector

3. Add the new property for external connector.
- EXTCON_PROP_DISP_HPD (Hot Plug Detect)

4. Add the new type of external connector.
- EXTCON_DISP_DP : Display Port
- EXTCON_DISP_HMD : Head Mounted Device
- EXTCON_CHG_WPT : Wireless Power Transfer device

5. Add the new extcon driver.
- Qualcomm SPMI PMIC USB id detection driver detects whether
EXTCON_USB_HOST is attached or detached. (extcon-qcom-spmi-mis.c)

6. Remove the usage of extcon_update_state() and old extcon_set_state()
- Both extcon_update_state() and extcon_set_state() should change the state
of all external connectors with bit masking handling. It may occur the
problem. Instead, extcon provides the extcon_set/get_state() functions.

7. Fix the minor issues on extcon drivers.
