Add support for high-boot on TQM5200 and TQM5200S boards.

Hint: the CPLD on the TQM5200 must be programmed with a software
version supporting the high boot option! The new TQM5200S is
already supporting this option. On the TQM5200 this option will be
supported in configurations with MPC5200 rev B processors.

To actually "high boot", set jumper X30 on the STK52xx.

 * Add support for new TQM5200 revisions
   - Support for TQM5200S (short version without graphic controller)
   - Support for modules with 'N' type S29GL128N Spansion flashes
     (requires changes to flash layout)
   - Support for MPC5200B cpu (mostly support for second SDRAM bank)
