MIPS: smp-cps: Enable all hardware interrupts on secondary CPUs

Browse source 
Currently interrupt vectors 2 and 5 are left disabled on secondary CPUs.
Since systems using CPS must also have a GIC, which is responsible for
routing all external interrupts and can map them to any hardware interrupt
vector, enable the remaining vectors.  The two software interrupt vectors
are left disabled since they are not used with CPS.
