bcm2836.c should be a self contained object, which its caller creates
and configures. The MachineClass is the board model object, and the
SoC object shouldn't have to access it. If there's something (like the
CPU model string) that the SoC needs, the SoC object should have a
property which the board model sets.

hw/arm/stm32f205_soc.c has an example of this (as do some of the
other SoC objects -- 'git grep cpu-type hw/arm' should bring them up).
