  2. pm: device: Dynamically add a device to a power domain 

    Add API to add devices to a power domain in runtime. The number of
devices that can be added is defined in build time.

The script gen_handles.py will check the number defined in
`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC` to resize the handles vector,
adding empty slots in the supported sector to be used later.

  2. Power Domain GPIO: Ensure init doesn’t fail if pin configuration fails 

    When a power domain is connected to another power domain,`pd_gpio_init` attempts to configure the gpio pin to `GPIO_DISCONNECTED`.

But if that failed, the init function returned -EIO, which caused the device to be marked as not initialized / ready.

This meant that it couldn’t be retrieved through `device_get_binding()`.
