[PATCH v2 04/17] iio: accel: mma9553: add enable channel for activity

[Irina Tirdea <irina.tirdea@intel.com>]

Since we need to specifically power on the device if used
in polling mode, we have an enable channel for each type
(step count, distance, speed, calories, etc.).

Add also an enable channel for activity, so it can also
be polled independently of events or other channels.
