So is it possible to completly disable the relocation process at startup and run U-Boot with having opcode in PROM and data in RAM? If yes, how could I achieve this?
I already tried to remove the corresponding code in the start.S and searched the README for switches, but without success.
Did you try the "CONFIG_SKIP_RELOCATE_UBOOT" ? I am not sure if it serves your purpose here. It depends upon whether or not your "start.S" uses it at all.

Tobias can try CONFIG_SKIP_RELOCATE_UBOOT, but it isn't likely to work as is. That flag is to configure u-boot to be loaded directly into RAM and run out of RAM (i.e. no relocation from flash to RAM). U-Boot was not designed to run from flash (aka. XIP - eXecute In Place) and nobody has done that as far as I know.
That doesn't mean u-boot cannot run XIP, it means that it will take an unknown amount of effort to make it happen.
