[PATCH 1/4] ARM: mmu: Call debug_ll_io_init if no map_io function is specified

[Maxime Ripard]

More and more sub-architectures are using only the debug_ll_io_init
function as the map_io function. Make the core code call this function
if no function is specified in the machine description to remove some
boilerplate code.
