[PULL 05/14] target/mips: Don't check COP1X for 64 bit FP mode |

From: Jiaxun Yang <jiaxun.yang@flygoat.com>
Some implementations (i.e. Loongson-2F) may decide to implement
a 64 bit FPU without implementing COP1X instructions.
As the eligibility of 64 bit FP instructions is already determined
by CP0St_FR, there is no need to check for COP1X again.
