The original ARM-only ioremap flavor 'ioremap_cached' has been renamed to 'ioremap_cache' to align with other architectures, and subsequently abused in generic code to map things like firmware tables in memory. For that reason, there is currently an effort underway to deprecate ioremap_cache, whose semantics are poorly defined, and which is typed with an __iomem annotation that is inappropriate for mappings of ordinary memory. However, original users of ioremap_cached() used it in a context where the I/O connotation is appropriate, and replacing those instances with memremap() does not make sense. So let's revive ioremap_cached(), so that we can change back those original users before we drop ioremap_cache entirely in favor of memremap.
