But the semantic of early_memreamp should be that it will just return
a normal memory pointer instead of iomem so the fix to convert the internal
implementation to return a __force __kernel make sense to me.

For iounmap I think since we have early_memremap, we have reason to add
early_memunmap() so sparse will be happy.

Thanks
