ODROID-N2/C4: arm64/dts: add PPS client device trees

Two device tree overlays are added to support GPS PPS client through GPIO pin header #11 and #12 as 'pps-gpio_p11.dtbo' and 'pps-gpio_p12.dtbo' respectively. Signed-off-by: Dongjin Kim <tobetter@gmail.com> Change-Id: I67c0a1750de0885e27b8545fab8acbd4ef0b7ef9
