Jiaxun Yang 166f0bf456 MIPS: cpu-features: Use boot_cpu_type for CPU type based features 
[ Upstream commit 5487a7b606 ]

Some CPU feature macros were using current_cpu_type to mark feature
availability.

However current_cpu_type will use smp_processor_id, which is prohibited
under preemptable context.

Since those features are all uniform on all CPUs in a SMP system, use
boot_cpu_type instead of current_cpu_type to fix preemptable kernel.
