correct conflict resolution in my opinion.

Subject: [PATCH] ARM: mach-shmobile: sh7372 map_io and init_early update
ARM: mach-shmobile: sh7372 map_io and init_early update
Update the sh7372 SoC and the AP4EVB and Mackerel boards to make use
of the functions sh7372_map_io() and sh7372_add_early_devices().
