Markos Chandras cea0f56822 MIPS: fpu.h: Allow 64-bit FPU on a 64-bit MIPS R6 CPU 
commit fcc53b5f6c upstream.

Commit 6134d94923 ("MIPS: asm: fpu: Allow 64-bit FPU on MIPS32 R6")
added support for 64-bit FPU on a 32-bit MIPS R6 processor but it missed
the 64-bit CPU case leading to FPU failures when requesting FR=1 mode
(which is always the case for MIPS R6 userland) when running a 32-bit
kernel on a 64-bit CPU. We also fix the MIPS R2 case.
