The bcm2837 is pretty similar to the bcm2836, but it does have some differences. Notably, the MPIDR affinity aff1 values it sets for the CPUs are 0x0, rather than the 0xf that the bcm2836 uses, and if this is wrong Linux will not boot. Rather than trying to have one device with properties that configure it differently for the two cases, create two separate QOM devices for the two SoCs. We use the same approach as hw/arm/aspeed_soc.c and share code and have a data table that might differ per-SoC. For the moment the two types don't actually have different behaviour.
