For some steps like HPD initialization this redundancy is not only an overhead but an actual problem, since they can't be run this early in the overall init sequence. Add a flag marking the init phase and skip reinitialzing state that is not strictly necessary based on that. This is also needed by the upcoming HPD init restructuring by Thierry and Daniel.
