MIPS: sync I/O related header files with linux-4.4
Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces. All files in that directory can be overwritten by a SoC/machine. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
