MIPS: Move KVM specific opcodes into asm/inst.h
The header arch/mips/kvm/opcode.h defines a few extra opcodes which aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM specific about them, so lets move them into inst.h where they belong and delete the header. Note that mfmcz_op is renamed to mfmc0_op to match the instruction set manual, and wait_op was already added to inst.h in commit b0a3eae2b943 ("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.
