This patch enables the support to perform selftest on PCIe endpoint driver present in the system. The following tests are currently performed by the selftest utility
- BAR Tests (BAR0 to BAR5)
- MSI Interrupt Tests (MSI1 to MSI32)
- Read Tests (For 1, 1024, 1025, 1024000, 1024001 Bytes)
- Write Tests (For 1, 1024, 1025, 1024000, 1024001 Bytes)

I'd suggest to resubmit this selftest after that.
Looks like we might end up removing the tests under tools/pci and just use this one. I will CC you on the v3 of PCI test cleanup series. Please rebase this patch on top of that and post after incorporating the review comments.
Thanks, Mani
