This patch series adds a new driver called xData-pcie for the Synopsys
DesignWare PCIe prototype.

The driver configures and enables the Synopsys DesignWare PCIe traffic
generator IP inside of prototype Endpoint which will generate upstream
and downstream PCIe traffic. This allows to quickly test the PCIe link
throughput speed and check is the prototype solution has some limitation
or not.

Changes:
 V2: Rework driver according to Greg Kroah-Hartman' feedback
 V3: Fixed issues detected while running on 64 bits platforms
     Rebased patches on top of v5.11-rc1 version
 V4: Rework driver according to Greg Kroah-Hartman' feedback
     Add the ABI doc related to the sysfs implemented on this driver
