Following patch fixes the XIP computation issue. I removed the normal image
because it was not working anyway (it was hardcoded) and because it allows me to
fix the XIP base to something sane (and use generic computation and approach)

This board is bit tricky because until now it required the VGA BIOS on the flash
start. XIP will work with 64KB aligned base, therefore the VGA ROM image must be
aligned too to 64KB.
