ARM: 6910/1: MTD: physmap: let set_vpp() pass a platform_device instead of a map_info

Browse Source 
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.
