remove the unnecessary rte_eal_pci_probe_one() in function
spdk_pci_device_detach(), this could cause error message when we
terminate the application, it will also not make sense try to probe one
device after we detach it, we could call spdk_pci_nvme_device_attach()
instead of spdk_pci_nvme_enumerate() when we have one given device address,
dpdk will try to scan the device and add it back to pci device list then.

This avoids registering PMDs that are not used by a given
application. For example, an app may wish to *not* use
ioat - in this case, ioat PMD would not be registered with
DPDK, and we would not waste time probing these devices
when probing other devices like NVMe.

This function will return a device handle from a pci
address.

If the first call to spdk_nvme_probe probes a device and
the driver elects not to take it, still call the probe
callback for that device on subsequence calls to
spdk_nvme_probe.

Change the PCI enumeration API to individual functions per device type
so that only the drivers that are actually in use get linked into the
final executable. All of the common code is still shared internally in
the env_dpdk library.

These functions will attach or detach from a PCI device. Attaching
typically means mapping the BAR.

Now that the env PCI framework already requires enumerating devices
based on an enum of specific device types, it is not useful to query the
class code of a PCI device handle.
It is currently unused and does not work in its current form on FreeBSD
(it reads a file from /sys). This lets us drop a big chunk of file
reading and parsing code.
