There is no need to define map_io only for debug_ll_io_init() since it
is already called in devicemaps_init() if map_io is NULL.
Apart from that, for NOMMU build debug_ll_io_init() is a nop which
leads to following error:
CC arch/arm/mach-imx/mach-imx1.o
arch/arm/mach-imx/mach-imx1.c:40:13: error: 'debug_ll_io_init' undeclared here (not in a function)
.map_io = debug_ll_io_init,
