I'm not sure if this is really what I think it is, but looking at the manual, CPU_nCNTHPIRQ[0] and [1] SPI ports and CNTHPIRQ PPI port seem to be the same signals, with the difference that the first two are shared interrupts connected through the combiner, while the last one is a per-processor interrupt, directly connected to GIC PPI port, allowing each CPU to get its own CNTHPIRQ signal ([0] for CPU 0 and [1] for CPU 1).
