powerpc/pci: Change how re-assigning resouces work
When PCI_REASSIGN_ALL_RSRC is set, we used to clear all bus resources at the beginning of survey and re-allocate them later. This changes it so instead, during early fixup, we mark all resources as IORESOURCE_UNSET and move them down to be 0-based. Later, if bus resources are still unset at the beginning of the survey, then we clear them. This shouldn't impact the re-assignment case on 4xx, but will enable us to have the platform do some custom resource assignment before the survey, by clearing individual resources IORESOURCE_UNSET bit. Also limits the clutter in the kernel log from fixup when re-assigning since we don't care about the offset applied to the BAR values in this case.
