The set_vpp() method provided by physmap passes a map_info back to the platform code, which has little relevance as far as the platform is concerned (this parameter is completely unused). Instead, pass the platform_device, which can be used in the pismo driver to retrieve some important information in a nicer way, instead of the hack that was in place. The empty set_vpp function in board-at572d940hf_ek.c is left untouched, as the board/SoC is scheduled for removal.
