s390/mm: provide simple ARCH_HAS_DEBUG_VIRTUAL support
Provide a very simple ARCH_HAS_DEBUG_VIRTUAL implementation.
For now errors are only reported for the following cases:
- Trying to translate a vmalloc or module address to a physical address
- Translating a supposed to be ZONE_DMA virtual address into a physical
address, and the resulting physical address is larger than two GiB
