Add support for MIPS32 and MIPS64 architectures:

- Remove all mmu-related code that may use 32 register on mips32-style
   implementatios and move them to mipsX_subr.S - which is then included
   from mips{3,32,64,5900}_subr.S with various control defines enabled.
 - Remove local cache instruction flags
 - Add badaddr64 (from Broadcom Corp).
