Hi,

This series carries forward the effort to add Kselftest for PCI Endpoint
Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version
based on another patch that fixes the return values of IOCTLs in
pci_endpoint_test driver and did many cleanups. Since the resulting work
modified the initial version substantially, I took over the authorship.

This series also incorporates the review comment by Shuah Khan [2] to move the
existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before
migrating to Kselftest framework. I made sure that the tests are executable in
each commit and updated documentation accordingly.

NOTE: Patch 1 is strictly not related to this series, but necessary to execute
Kselftests with Qualcomm Endpoint devices. So this can be merged separately.

Changes in v2:

* Added a patch that fixes return values of IOCTL in pci_endpoint_test driver
* Moved the existing tests to new location before migrating
* Added a fix for BARs on Qcom devices
* Updated documentation and also added fixture variants for memcpy & DMA modes
