To avoid dereferencing hardwired constant pointers from a global header file, change the driver to use devm_platform_ioremap_resource for getting an __iomem pointer, and then using readl/writel on that. Each pointer dereference gets changed by a search&replace, which leads to a few overlong lines, but seems less risky than trying to clean up the code at the same time.
