Philippe Mathieu-Daudé d82ab2931d hw/misc/pca9552: Trace GPIO change events 
Emit a trace event when a GPIO change its state.

Example booting obmc-phosphor-image:

  $ qemu-system-arm -M witherspoon-bmc -trace pca955x_gpio_change
  1592690552.687372:pca955x_gpio_change pca1 GPIO id:0 status: 0 -> 1

We notice the GPIO #14 (front-power LED) starts to blink.

This LED is described in the witherspoon device-tree [*]:

  front-power {
      retain-state-shutdown;
      default-state = "keep";
      gpios = <&pca0 14 GPIO_ACTIVE_LOW>;
  };
