Subject: [PATCH v2 0/5] misc: Improvements to pci_endpoint_test driver

This series adds improvements and fixes to pci_endpoint_test driver
mostly applicable when used with multi-function endpoint (or multiple
endpoint instances using pci_epf_test).

*) Using module parameter to determine irqtype would indicate all the
   pci_endpoint_test device have the same irqtype. Fix it here.
*) Add ioctl to clear irq so that "cat /proc/interrupts" only lists
   the entries for the devices that is actually being used.
*) Creating more than 10 pci-endpoint-test devices results in a kernel
   error.
*) Use full pci-endpoint-test name in request irq so that it's easy to
   profile the interrupt details in "cat /proc/interrupts"

Changes from v1:
*) Removed a patch that references J721E device ID (That patch will
   be added as part of J721E support series)
*) Removed a patch that always enable legacy interrupt. That should
   be handled by pci_alloc_irq_vectors()
