Merge branch 'pci/misc'

- Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device so dwc3 can
  claim it instead (Vicki Pfau)

- Make pci_assign_unassigned_resources() non-init because sparc uses it
  after init-time (Randy Dunlap)

- Remove logic_outb(), _outw(), outl() duplicate declarations (John Sanpe)

- Remove unnecessary UTF-8 in Kconfig help text that confuses menuconfig
  (Liu Song)

- Fix double free in __pci_epc_create() (Dan Carpenter)

- Simplify pcie_capability_clear_and_set_word() cases that could be
  pcie_capability_clear_word() (Ilpo Järvinen)

* pci/misc:
  PCI: Simplify pcie_capability_clear_and_set_word() to ..._clear_word()
  PCI: endpoint: Fix double free in __pci_epc_create()
  PCI: Replace unnecessary UTF-8 in Kconfig
  logic_pio: Remove logic_outb(), _outw(), outl() duplicate declarations
  PCI: Make pci_assign_unassigned_resources() non-init
  PCI: Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device
