Harinath Nampally 605f72de13 iio: accel: mma8452: improvements to handle multiple events 
This driver supports multiple devices like mma8653,
    mma8652, mma8452, mma8453 and fxls8471. Almost all
    these devices have more than one event.

    Current driver design hardcodes the event specific
    information, so only one event can be supported by this
    driver at any given time.
    Also current design doesn't have the flexibility to
    add more events.

    This patch improves by detaching the event related
    information from chip_info struct,and based on channel
    type and event direction the corresponding event
    configuration registers are picked dynamically.
    Hence both transient and freefall events can be
    handled in read/write callbacks.

    Changes are thoroughly tested on fxls8471 device on imx6UL
    Eval board using iio_event_monitor user space program.

    After this fix both Freefall and Transient events are
    handled by the driver without any conflicts.
