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.
