MIPS: pm-cps: Generate idle state entry code when CPUs are onlined The MIPS Coherent Processing System (CPS) power management code has previously generated code used to enter low power idle states once during boot for all CPUs. This has the drawback that if a CPU is present in the system but not being used (for example due to the maxcpus kernel parameter) then we encounter problems due to not having probed that CPU for information about its type & properties. The result of this is that we generate entry code which is both unused, potentially entirely invalid & likely to be unsuitable for the CPU in question anyway. Avoid this by generating idle state entry code only when a CPU is brought online. This way we only ever generate code for CPUs that we know we've probed the properties of, and that will actually be used.
