s390/mm: rename POPULATE_ONE2ONE to POPULATE_DIRECT
Architectures generally use the "direct map" wording for mapping the whole
physical memory. Use that wording as well in arch/s390/boot/vmem.c, instead
of "one to one" in order to avoid confusion.
This also matches what is already done in arch/s390/mm/vmem.c.
