Input: add support for polling to input devices
Separating "normal" and "polled" input devices was a mistake, as often we want to allow the very same device work on both interrupt-driven and polled mode, depending on the board on which the device is used. This introduces new APIs: - input_setup_polling - input_set_poll_interval - input_set_min_poll_interval - input_set_max_poll_interval These new APIs allow switching an input device into polled mode with sysfs attributes matching drivers using input_polled_dev APIs that will be eventually removed.
