Two comments on this one:
* I wonder if we could just kill off some of the mappings if no driver
relies on the registers being mapped in advance, especially for those
that don't benefit from section mapping like the ethernet one that is
only a page anyway.
* I would recommend defining the IO_ADDRESS macro in a way that the
result is of type 'void __iomem *', and you add a cast in the
map_desc array. We will probably clean those up eventually and
require that they are pointers at that place anyway, based on
recent discussions.
