target/mips: Convert Vr54xx MUL* opcodes to decodetree
Convert the following Integer Multiply-Accumulate opcodes:
* MULHI Multiply and move HI
* MULHIU Unsigned multiply and move HI
* MULS Multiply, negate, and move LO
* MULSHI Multiply, negate, and move HI
* MULSHIU Unsigned multiply, negate, and move HI
* MULSU Unsigned multiply, negate, and move LO
