artecgroup/dbe61: 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@0xffc00000 for FILO with 4MB minus ROM area
available.

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

The same change was done to artecgroup/dbe62/stage1.c in rev660.

Unless someone has a huge problem with this (I don't)

so you're booting? Do we have your RAM setup commit?

I don't like it that much, but then again, nothing else on this board
will ever listen to port 0x88.
