Changes to fpga_region_register function to not set drvdata. Setting drvdata is fine for DT based devices that will have one region per platform device. However PCIe based devices may have multiple FPGA regions under one PCIe device. Without these changes, the PCIe solution has to create an extra device for each child region to hold drvdata.
