Add BAR_SUBRANGE_TEST to the pci_endpoint kselftest suite. The test uses the PCITEST_BAR_SUBRANGE ioctl and will skip when the chosen BAR is disabled (-ENODATA), when the endpoint/controller does not support subrange mapping (-EOPNOTSUPP), or when the BAR is reserved for the test register space (-EBUSY).
