ODROID-N2/C4: dtbs/dtbo: add PPS via GPIO pin #11/#12

Browse Source 
This patch addes two device tree overlay files in order to run PPS via
GPIO pins populated in GPIO pin header #11 and #12. By adding the device
tree overlay file to 'config.ini', the driver will be enabled and PPS
will be registered.

In 'config.ini',

	overlays="pps-gpio_p12"
