[PULL 13/26] hw/mips: Move address translation helpers to target/mips/

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Address translation is an architectural thing (not hardware
related). Move the helpers from hw/ to target/.

As physical address and KVM are specific to system mode
emulation, restrict this file to softmmu, so it doesn't
get compiled for user-mode emulation.
