[PATCH v3 4/7] 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
1592693373.997015:led_change_intensity LED desc:'front-fault-4' color:green
intensity 0x0000 -> 0xffff
1592693373.997632:led_change_intensity LED desc:'front-power-3' color:green
intensity 0x0000 -> 0xffff
1592693373.998239:led_change_intensity LED desc:'front-id-5' color:green
intensity 0x0000 -> 0xffff
1592693500.291805:led_change_intensity LED desc:'front-power-3' color:green
intensity 0xffff -> 0x0000
1592693500.312041:led_change_intensity LED desc:'front-power-3' color:green
intensity 0x0000 -> 0xffff
1592693500.821254:led_change_intensity LED desc:'front-power-3' color:green
intensity 0xffff -> 0x0000
1592693501.331517:led_change_intensity LED desc:'front-power-3' color:green
intensity 0x0000 -> 0xffff
1592693501.841367:led_change_intensity LED desc:'front-power-3' color:green
intensity 0xffff -> 0x0000
1592693502.350839:led_change_intensity LED desc:'front-power-3' color:green
intensity 0x0000 -> 0xffff
1592693502.861134:led_change_intensity LED desc:'front-power-3' color:green
intensity 0xffff -> 0x0000
1592693503.371090:led_change_intensity LED desc:'front-power-3' color:green
intensity 0x0000 -> 0xffff
We notice the front-power LED starts to blink.
