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.
