lis3: add click function
The LIS302DL accelerometer chip has a 'click' feature which can be used to detect sudden motion on any of the three axis. Configuration data is passed via spi platform_data and no action is taken if that's not specified, so it won't harm any existing platform. To make the configuration effective, the IRQ lines need to be set up appropriately. This patch also adds a way to do that from board support code. The DD_* definitions were factored out to an own enum because they are specific to LIS3LV02D devices.
