Add support for parallax ping and laser ping sensors with just one pin for trigger and echo signal. This driver is based on srf04. In contrast to it it's necessary to change direction of the pin and to request the irq just for the period when the echo is rising and falling. Because this adds a lot of cases there is this individual driver for handling this type of sensors. Add a new configuration variable CONFIG_PING to Kconfig and Makefile. Julia reported an issue with failing to unlock a mutex in some error paths.
