Merge branches 'pci/host-dra7xx', 'pci/host-imx6' and 'pci/host-spear' into next 

* pci/host-dra7xx:
  PCI: dra7xx: Remove unneeded use of IS_ERR_VALUE()

* pci/host-imx6:
  PCI: imx6: Simplify a trivial if-return sequence

* pci/host-spear:
  PCI: spear: Use BUG_ON() instead of condition followed by BUG()
