/**
* @brief Check if all `DT_DRV_COMPAT` node with status `okay` has a given
* boolean property that exists. If all nodes are disabled, this
* will return 1.
* *
* @param prop lowercase-and-underscores property name
*
* Example devicetree overlay:
*
* @code{.dts}
* &i2c0 {
* sensor0: sensor@0 {
* compatible = "vnd,some-sensor";
* status = "okay";
* reg = <0>;
* foo;
* bar;
* };
*
* sensor1: sensor@1 {
* compatible = "vnd,some-sensor";
* status = "okay";
* reg = <1>;
* foo;
* };
*
* sensor2: sensor@2 {
* compatible = "vnd,some-sensor";
* status = "disabled";
* reg = <2>;
* baz;
* };
* };
* @endcode
*
* Example usage:
*
* @code{.c}
* #define DT_DRV_COMPAT vnd_some_sensor
*
* DT_ALL_INST_HAS_BOOL_STATUS_OKAY(foo) // 1
* DT_ALL_INST_HAS_BOOL_STATUS_OKAY(bar) // 0
* DT_ALL_INST_HAS_BOOL_STATUS_OKAY(baz) // 0
* @endcode
