This is the last patch in the series which implements the essentials of the
Movable BARs feature, so it is turned by default now. Tested on:

 - x86_64 with "pci=realloc,pcie_bus_peer2peer" command line argument;
 - POWER8 PowerNV+PHB3 ppc64le with "pci=realloc,pcie_bus_peer2peer".

In case of problems it is still can be overridden by the following command
line option:

  pcie_movable_bars=off
