Hello,

These patches are part of the GSoC unselected 'QEMU visualizer'
project.  As the AVR port is not merged, I switched to microbit
to keep working on it.

This series presents a proof of concept of LED device that can
be easily connected to a GPIO.

Since v2:
- Rebased on PCA9552
- Model intensity to be ready for PWM use (Dave)
- Remove QMP events until we get a UI visualizer (Peter)
- Remove microbit patch (Peter)

Since v1: addressed Eric Blake review comments
- Added QMP rate limit

Next steps planned:

- PoC visualizer...
- look at using a dbus backend (elmarco)
- look at LED array/matrix such 7segments.

Regards,

Phil.
