MIPS: Netlogic: rename nlm_cop2_save/restore 

Rename macro nlm_cop2_enable() to nlm_cop2_enable_irqsave() and the macro
nlm_cop2_restore to nlm_cop2_disable_irqrestore(). The new names will
reflect the functionality better, and will make nlm_cop2_restore()
available to be used later in COP2 save/restore patch.
