PCI/IDE: Report available IDE streams
The limited number of link-encryption (IDE) streams that a given set of host bridges supports is a platform specific detail. Provide pci_ide_init_nr_streams() as a generic facility for either platform TSM drivers, or PCI core native IDE, to report the number available streams. After invoking pci_ide_init_nr_streams() an "available_secure_streams" attribute appears in PCI host bridge sysfs to convey that count. Introduce a device-type, @pci_host_bridge_type, now that both a release method and sysfs attribute groups are being specified for all 'struct pci_host_bridge' instances.
