SCIF0 and SCIF1 are used as debug serial ports. Enable them and configure pinmuxing appropriately. We can now remove the clkdev registration hack for SCIF devices from the Lager reference board file. As a side effect of switching to DT-based serial port instantiation, ttySC6 and ttySC7 get renamed to ttySC0 and ttySC1. As the device tree source if now shared between lager and lager-reference, we need to update the serial ports in C code as well.
