Adapt board configuration and fix kernel crash on MCC200 board.
The update procedure was modified to turn off the USB subsystem before exit for MCC200 and TRAB. This is necessary as otherwise the USB controller continues to write periodically to system memory! MCC200-specific notes: - the patch disables the magic key check for MCC200 - the patch contains the configuration changes made for the new revision of the board.
