[U-Boot-Users] [PATCH] 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).
