ARM: shmobile: EMEV2 map_io update
Update the EMEV2 struct map_desc to exclude the SMU
and also include the ->map_io() callback in the DT
version of EMEV2 board support.
The EMEV2 SMP code can these days perform ioremap()
early on without the SMU information in the io_desc[].
To correctly support SMP in case of DT-only board
support then the ->map_io() callback is needed.
