hw/arm/aspeed: Add the 3 front LEDs drived by the PCA9552 #1
The Witherspoon has 3 LEDs connected to a PCA9552. Add them.
The names and reset values are taken from:
https://github.com/open-power/witherspoon-xml/blob/master/witherspoon.xml
Example booting obmc-phosphor-image:
$ qemu-system-arm -M witherspoon-bmc -trace led_change_intensity

1592693503.371090:led_change_intensity LED desc:'front-power-3' color:green intensity 0% -> 100%
We notice the front-power LED starts to blink at a ~2Hz rate.
