PnP: move pnpacpi/pnpbios_init to after PCI init
We already did that a long time ago for pnp_system_init, but pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get linked into the kernel before the arch-specific routines that finalize the PCI resources (pci_subsys_init). This means that the PnP routines would either register their resources before the PCI layer could, or would be unable to check whether a PCI resource had already been registered. Both are problematic. I wanted to do this before 2.6.27, but every time we change something like this, something breaks. That said, _every_ single time we trust some firmware (like PnP tables) more than we trust the hardware itself (like PCI probing), the problems have been worse.
