PCI: mt7621: Move MIPS setup to pcibios_root_bridge_prepare()

On the MIPS ralink mt7621 platform, we need to set up I/O coherency units
based on the host bridge apertures.

To remove this arch dependency from the driver itself, move the coherency
setup from the driver to pcibios_root_bridge_prepare().
