MIPS: mipsregs.h: Move TX39 macros out of the way

TX39 CP0 Configuration Register 3 macro definitions have been randomly
thrown in the middle of a block of CP0 Status register value macros.
Move them to the end of the whole CP0 register value macro block,
complementing the location of the TX39 Cache register name macro at the
end of the CP0 register name macro block.
