Issue 828: add PPS driver for GTA04A5 GPS module

Reported by Nikolaus Schaller, Jul 21, 2017

see https://www.kernel.org/doc/Documentation/pps/pps.txt
and 
http://elixir.free-electrons.com/linux/v4.13-rc1/source/Documentation
/devicetree/bindings/pps/pps-gpio.txt

So we mainly need to add pinmux and

	pps {
		compatible = "pps-gpio";
		gpios = <&gpio2 18 0>; /* GPIN114 */

		// assert-falling-edge;
	};

to omap3-gta04a5.dts

Note: PPS is only available if some client has opened /dev/ttyGPS0

Sidenote: we should add the package "pps-tools" to the 
Letux.deb useful tools.
