//  Function:  OALKitlInitRegistry
//
//  This function is called as part of IOCTL_HAL_INITREGISTRY to update
//  registry with information about KITL device. This must be done to avoid
//  loading Windows CE driver in case that it is part of image. On image
//  without KITL is this function replaced with empty stub.
//
//  This implementation works only for PCI KITL devices. It probably should
//  be replaced with platform specific code if KITL device is on internal
//  bus.
