Per the 'ARM MPS2 and MPS2+ FPGA Prototyping Boards Technical
Reference Manual' (100112_0200_07_en):
2.1 Overview of the MPS2 and MPS2+ hardware
The MPS2 and MPS2+ FPGA Prototyping Boards contain the
following components and interfaces:
* User switches and user LEDs:
- Two green LEDs and two push buttons that connect to
the FPGA.
- Eight green LEDs and one 8-way dip switch that connect
to the MCC.
Add the 8 LEDs connected to the MCC.
This replaces the 'mps2_scc_leds' trace events by the generic
'led_set_intensity' event.
