Subject: [RFC 00/10] Adds pcitest tool support for MSI-X

This patch set depends the following series:
https://lkml.org/lkml/2018/4/10/421

This series aims to add pcitest tool support for MSI-X. 

Includes new callbacks methods and handlers to trigger the MSI-X
interruptions on the EP Designware IP driver.

Provides new methods on pci_epf_test driver that allows to set/get
EP maximum number of MSI-X entries (similar to set/get MSI methods).

Reworks on MSI set/get and triggering methods on EP Designware IP driver
to be more generic and flexible.

Adds a new input parameter (msix) and replicates the whole MSI mechanism
applied to the MSI-X feature on pcitest tool. Also updates the pcitest
script with the new test set applied to this new feature.

  PCI: dwc: Add MSI-X callbacks handler
  PCI: cadence: Update cdns_pcie_ep_raise_irq function signature
  PCI: endpoint: Add MSI-X interfaces
  PCI: dwc: MSI callbacks handler rework
  PCI: dwc: Add legacy interrupt callback handler
  misc: pci_endpoint_test: Add MSI-X support
  misc: pci_endpoint_test: Replace lower into upper case characters
  PCI: endpoint: functions/pci-epf-test: Add MSI-X support
  PCI: endpoint: functions/pci-epf-test: Replace lower into upper case
    characters
  tools: PCI: Add MSI-X support
