Revert "s390: Relocate vmlinux ELF data to virtual address space"

This reverts commit 9ecaa2e9.

In case CONFIG_MODULES kernel option is not defined the build fails
with the following linker error:

block/partitions/ibm.o: in function `ibm_partition':
ibm.c:(.text+0x8bc): relocation truncated to fit: R_390_PLT32DBL against undefined symbol `dasd_biodasdinfo'
