Add support for TQM8541/8555 boards, TQM85xx support reworked:
- Support for TQM8541/8555 boards added. - Complete rework of TQM8540/8560 support. - Common TQM85xx code now supports all current TQM85xx platforms (TQM8540/8541/8555/8560). - DDR SDRAM size detection added. - CAS latency default values can be overwritten by setting "serial#" to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used. If problems are detected with this non default CAS latency, the defualt values will be used instead. - FLASH size detection added. - Moved FCC ethernet driver initialization behind TSEC driver init -> TSEC is first device.
