target/mips: Move helper_cache() to tcg/sysemu/special_helper.c
Move helper_cache() to tcg/sysemu/special_helper.c.
The CACHE opcode is privileged and is not accessible in user
emulation. However we get a link failure when restricting the
symbol to sysemu. For now, add a stub helper to satisfy linking,
which abort if ever called.
