-- v7

* Revert removal of RTE_VERIFY on find_device operation since a bus that isn't
  able to even iterate its devices is pointless

* Revert plug() changes that have been introduced in v3:
  int (*rte_bus_plug_t)(struct rte_device *dev, const char *devargs);

* Revert pointless reordering of start argument for bus iterator functions

* Add fslmc bus find_device operation

* Add support to find a bus by its name

* Add EAL hotplug API:
  int rte_eal_hotplug_add(const char *busname, const char *devname,
                          const char *devargs);
  int rte_eal_hotplug_remove(const char *busname, const char *devname);

* Keep rte_eal_dev_attach() backwards compatible and support hotplug of PCI
  and virtual devices only

* Add back patch "ethdev: use embedded rte_device to detach driver" which is
  critical for correctly detaching the correct low-level device

-- v8

* Rework rte_eal_dev_detach to break API and remove rte_eal_device_detach

* Drop "bus: add bus iterator to find a device" since its not actively used

* Adjust coding style to explicitly check against NULL pointer


* Fix exporting of new bus function symbols
