artecgroup/dbe62: Set up 4MB mode for LPC dongle

This way we can fit a kernel and initramfs on the dongle's free ~3.75MB space and have a debug system bootable right from inside the dongle.
The start address of the dongle is mem at 0xffc00000 for FILO with 4MB minus ROM area available.

For your consideration of suitability for stage1 mainboard setup.
