You should normally be able to completely avoid the ->map_io() hook. If
you leave it set to NULL, it will automatically call
debug_ll_io_init(), which will setup the virt->phys mapping needed by
DEBUG_LL stuff. All the other mappings will be created dynamically with
ioremap().
The static mapping covering all registers is really no longer needed.
