Break out the MI part of the /dev/[k]mem and /dev/io drivers into their own directory and module, leaving the MD parts in the MD area (the MD parts _are_ part of the modules). /dev/mem and /dev/io are now loadable modules, thus taking us one step further towards a kernel created entirely out of modules. Of course, there is nothing preventing the kernel from having these statically compiled.

Add reader/writer lock around mem_range_attr_get() and mem_range_attr_set(). Compile sys/dev/mem/memutil.c for all supported platforms and remove now unnecessary dev_mem_md_init(). Consistently define mem_range_softc from mem.c for all platforms. Add missing #include guards for machine/memdev.h and sys/memrange.h. Clean up some nearby style(9) nits. MFC after: 1 month
