ide: add ->dev and ->host_priv fields to struct ide_host

* Add 'struct device *dev[2]' and 'void *host_priv' fields
  to struct ide_host.

* Set ->dev[] in ide_host_alloc_all()/ide_setup_pci_device[s]().

* Pass 'void *priv' argument to ide_setup_pci_device[s]()
  and use it to set ->host_priv.

* Set PCI dev's ->driver_data to point to the struct ide_host
  instance if PCI host driver wants to use ->host_priv.

* Rename ide_setup_pci_device[s]() to ide_pci_init_{one,two}().
