Implement Root Bus FDO AddDevice codes, get boot config, connect to HAL or ACPI config handlers (PciQueryForPciBusInterface, PciGetConfigHandlers), read BUS FDO hack flag, get _HPP HotPlug PCI ACPI data and initialize arbiter support.
PciGetHotPlugParameters work but no PCI HotPlug support on my machines, so cannot test ACPI data, that part stub now
Add PciFdoDispatchTable, PciFdoDispatchPnpTable, PciFdoDispatchPowerTable but all stub to PciIrpNotSupported however set correct IRP Dispatch Style for the IRPS
Arbiter support in PciInitializeARbiters done, but PciInterfaces array is NULL (stub) at moment
Add PCI_SIGNATURE, PCI_STATE, PCI_DISAPTCH_STYLE type, add PciInitializeState to begin the state support
Add structure for PCI_FDO_EXTENSION, PCI_SECONDARY_EXTENSION, PCI_INTERFACE, PCI_ARBITER_INSTANCE, PCI_DISPATCH_TABLE
PCI utility functions added: PciFindParentPciFdoExtension, PciInsertEntryAtTail, PciInsertEntryAtHead, PcipLinkSecondaryExtension, PciGetDeviceProperty, PciSendIoctl
Need sir_richard to add arbiter.h header to define ARBITER_INSTANCE for finish support
This 1000 more codes done now~
