Paul Burton d642e4e7b4 MIPS: smp-cps: Clear Status IPL field when using EIC 
When using an external interrupt controller (EIC) the interrupt mask
bits in the cop0 Status register are reused for the Interrupt Priority
Level, and any interrupts with a priority lower than the field will be
ignored. Clear the field to 0 by default such that all interrupts are
serviced.
