Rob Herring 304a39b4bc dt-bindings: more status property removal from examples
Whack-a-mole some more occurrences of status in examples.

Device-Tree Bindings for a PPS Signal on GPIO
These properties describe a PPS (pulse-per-second) signal connected to
a GPIO pin.
Required properties:
- compatible: should be "pps-gpio"
- gpios: one PPS GPIO in the format described by ../gpio/gpio.txt
Optional properties:
- assert-falling-edge: when present, assert is indicated by a falling edge
(instead of by a rising edge)
Example:
pps {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pps>;
gpios = <&gpio1 26 GPIO_ACTIVE_HIGH>;
assert-falling-edge;
compatible = "pps-gpio";
};
