[PATCH v1 2/2] counter: add GPIO based pulse counters

Add simple GPIO base pulse counter. This device is used to measure rotation speed of some agricultural devices, so no high frequency on the counter pin is expected. The maximal measurement frequency depends on the CPU and system load. On the idle iMX6S I was able to measure up to 20kHz without cou
