The wait instruction encoding changed between ISA v2.07 and ISA v3.0.
In v3.1 the instruction gained a new field.
Update the PPC_WAIT macro to the current encoding. Rename the older

In fsl_pci_assign_primary(), we should remove the of_node_put()
when breaking out of the for_each_matching_node() as the 'np'
is escaped out by global 'fsl_pci_primary'.

The definition of the pci header function pci_get_legacy_ide_irq is only
used in platforms that support PNP. So many of the architecutres where
it is defined do not use it. This also means we can remove

During recent PCI cleanups we noticed that the isa_dma_bridge_buggy
