<div class='commit-subject'>ARM: i.MX: remove map_io callback</div><div class='commit-msg'>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:
