extcon: Move defintion of struct extcon_dev to driver/extcon directory
This patch moves the 'struct extcon_dev' of extcon subsystem
to driver/extcon/extcon.h header file because the struct extcon_dev have to
be handled by extcon API to guarantee the consistency of strcut extcon_dev.
If external drivers are able to touch the struct extcon_dev directly, it might
cause the critical and unknown problem.

- * struct extcon_dev - An extcon device represents one external connector.
- * @name: The name of this extcon device. Parent device name is
- * used if NULL.
- * @supported_cable: Array of supported cable names ending with EXTCON_NONE.
- * If supported_cable is NULL, cable name related APIs
- * are disabled.
- * @mutually_exclusive: Array of mutually exclusive set of cables that cannot
- * be attached simultaneously. The array should be
- * ending with NULL or be NULL (no mutually exclusive
- * cables). For example, if it is { 0x7, 0x30, 0}, then,
- * {0, 1}, {0, 1, 2}, {0, 2}, {1, 2}, or {4, 5} cannot
- * be attached simulataneously. {0x7, 0} is equivalent to
- * {0x3, 0x6, 0x5, 0}. If it is {0xFFFFFFFF, 0}, there
- * can be no simultaneous connections.
- * @dev: Device of this extcon.
- * @state: Attach/detach state of this extcon. Do not provide at
- * register-time.
- * @nh: Notifier for the state change events from this extcon
- * @entry: To support list of extcon devices so that users can
- * search for extcon devices based on the extcon name.
- * @lock:
- * @max_supported: Internal value to store the number of cables.
- * @extcon_dev_type: Device_type struct to provide attribute_groups
- * customized for each extcon device.
- * @cables: Sysfs subdirectories. Each represents one cable.
- *
- * In most cases, users only need to provide "User initializing data" of
- * this struct when registering an extcon. In some exceptional cases,
- * optional callbacks may be needed. However, the values in "internal data"
- * are overwritten by register function.
