TQM85xx: Fix CPM port pin configuration
Do not configure port pins PD30/PD31 as SCC1 TxD/RxD except for the TQM8560 board. On the other TQM85xx boards (TQM8541 and TQM8555) SCC1 is not used as serial interface anyway. Worse, on some board variants configuring the pins for SCC1 leads to short circuits (for example on the TQM8541-BG). Signed-off-by: Martin Krause <martin.krause@tqs.de>
