MIPS: Add kernel_pref & user_pref helpers 
Add kernel_pref & user_pref macros to asm/asm-eva.h, providing an
abstraction around EVA & non-EVA pref instructions consistent with the
existing macros we have for cache & load/store instructions.

9324494595 MIPS: asm: Add wrappers for EVA/non-EVA instructions 
EVA uses specific instructions for accessing user memory.
Instead of polluting the kernel with numerous #ifdef CONFIG_EVA
we add wrappers for all the instructions that need special
handling when EVA is enabled.
