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

This should be a no-op when not booting from the dongle.
