[PATCH] MIPS: Fix for warning from FPU emulation code

["Jayachandran C" <jchandra@broadcom.com>]

The default implementation of 'cpu_has_fpu' macro calls
smp_processor_id() which causes this warning to be printed when
preemption is enabled:

[    4.664000] Algorithmics/MIPS FPU Emulator v1.5
[    4.676000] BUG: using smp_processor_id() in preemptible [00000000] code: ini
[    4.700000] caller is fpu_emulator_cop1Handler+0x434/0x27b8

Use 'raw_cpu_has_fpu' macro in cop1_64bit() instead of 'cpu_has_fpu'
to fix this. Fix suggested by Ralf Baechle <ralf@linux-mips.org>
