motivation behind of this patch:
- bring build coverage for NOMMU configurations
- allow known working NOMMU platforms (like R-class) to be used
- pave a way to add support for single address space (aka 1:1 mapping)
  for MMU platforms, so they can be usable in NOMMU configurations

I use XIP_KERNEL with a MMU platform (Renesas RZ/A1, Cortex A9) which is
also ARCH_MULTIPLATFORM.

So I also have to hack the Kconfig to get it to build.

I had proposed this patch to allow you to select which multiplatform
devices are XIP capable, but it never made it in.

Maybe you can do the same idea for !MMU platforms as well (just
say whether the device can do XIP regardless of MMU or !MMU)
