MIPS: Move content of arch/mips/cpu to arch/mips/cpu/mips32

All current CPUs and SoCs are based on MIPS32 arch. The complete
code resides in the global arch/mips/cpu directory. This is not
suitable if other MIPS architectures like MIPS64 or Octeon should
be supported in the future.

To achieve this the current CPU code is moved to its own mips32
subdirectory. All MIPS32 boards have to use mips32 as config switch
in board.cfg.
