Merge branch 'pci/irq-clean-up'

- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more explicit and match spec
  terminology (Bjorn Helgaas)

- Use existing PCI_IRQ_INTX, PCI_IRQ_MSI, PCI_IRQ_MSIX in artpec6, cadence,
  designware, designware-plat, dra7xx, imx6, keembay, keystone, layerscape,
  mhi, ntb, qcom, rcar, rcar-gen4, rockchip, tegra194, uniphier, vntb; drop
  the redundant pci_epc_irq_type enum with the same values (Damien Le Moal)

- Use "intx" instead of "leg" or "legacy" when describing INTx interrupts
  in endpoint core, endpoint tests, cadence, dra7xx, designware,
  dw-rockchip, dwc core, imx6, keystone, layerscape, qcom, rcar-gen4,
  rockchip, tegra194, uniphier, xilinx-nwl (Damien Le Moal)

* pci/irq-clean-up:
  PCI: xilinx-nwl: Use INTX instead of legacy
  PCI: rockchip-host: Rename rockchip_pcie_legacy_int_handler()
  PCI: rockchip-ep: Use INTX instead of legacy
  PCI: uniphier: Use INTX instead of legacy
  PCI: tegra194: Use INTX instead of legacy
  PCI: dw-rockchip: Rename rockchip_pcie_legacy_int_handler()
  PCI: keystone: Use INTX instead of legacy
  PCI: dwc: Rename dw_pcie_ep_raise_legacy_irq()
  PCI: cadence: Use INTX instead of legacy
  PCI: dra7xx: Rename dra7xx_pcie_raise_legacy_irq()
  misc: pci_endpoint_test: Use INTX instead of LEGACY
  PCI: endpoint: Rename LEGACY to INTX in test function driver
  PCI: endpoint: Use INTX instead of legacy
  PCI: endpoint: Drop PCI_EPC_IRQ_XXX definitions
  PCI: Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX
