PCI: Remove legacy pcim_release()

Thanks to preceding cleanup steps, pcim_release() is now not needed
anymore and can be replaced by pcim_disable_device(), which is the exact
counterpart to pcim_enable_device().

This permits removing further parts of the old PCI devres implementation.

Replace pcim_release() with pcim_disable_device().  Remove the now unused
function get_pci_dr().  Remove the struct pci_devres from pci.h.
