Too many drivers use all sorts of different types, I've given up
hope of changing drivers to agree on the same type here. Basically
you can think of 'void __iomem *' as the magic keyword for something
that gets returned from ioremap, can take an integer offset and gets
passed into readb/readw/readl/write..., but any other assumption beyond
that is dangerous.
