PCI: Move struct pci_devres.pinned bit to struct pci_dev

The bit describing whether the PCI device is currently pinned is stored
in struct pci_devres. To clean up and simplify the PCI devres API, it's
better if this information is stored in struct pci_dev.

This will later permit simplifying pcim_enable_device().

Move the 'pinned' boolean bit to struct pci_dev.

Restructure bits in struct pci_dev so the pm / pme fields are next to
each other.
