Routine Description:
This routine searches the PCI device tree to see if the specific device
is present in the system. Not devices that are explicitly not enumerated
(such as PIIX4 power management function) are considered absent.
Arguments:
VendorID - Required VendorID of the device
DeviceID - Required DeviceID of the device
RevisionID - Optional Revision ID
SubVendorID - Optional Subsystem Vendor ID
SubSystemID - Optional Subsystem ID
Flags - Bitfield which indicates if Revision and Sub* ID's should be used:
PCI_USE_SUBSYSTEM_IDS, PCI_USE_REVISION_ID are valid all other bits
should be 0
Return Value:
TRUE if the device is present in the system, FALSE otherwise.

Routine Description:
This routine searches the PCI device tree for a given device

Arguments:
FdoExtension - A pointer to the device extension of a PCI FDO.
This represents the bus to be searched for the given device.
PdoExtension - A pointer to the device extension of the PCI PDO that requested
the search. Some device searches are limited to the same bus/device number
as the requesting device, and this is used to get those numbers.
Parameters - The parameters of the search.
Flags - A bitfield indicating which fields of the Parameters structure to use for the search.
