[PATCH 0/3] fpga: don't use drvdata in common fpga code

[Alan Tull]

This patch set goes on top of the non-dt set that's been on
the list since March.  

This patchset changes the following fpga_*_register functions to not
set drvdata:
* fpga_region_register.
* fpga_mgr_register
* fpga_bridge_register

Setting drvdata is fine for DT based devices, that will have one
manager, bridge, or region device per platform device.  PCIe based
devices may have multiple FPGA mgr/bridge/regions under one pcie
device.  Without these changes, PCIe-based solutions have to create an
extra device for each child mgr/bridge/region to hold drvdata.

Other changes:

- pass mgr to fpga_mgr_register/unregister instead of dev.
- pass bridge to fpga_bridge_register/unregister.
- Callers of fpga_bridge/mgr_register, are changed to alloc the
bridge/mgr struct and partly fill it, adding name, ops and priv.
- Caller uses devm for allocating the mgr/bridge structures.
- The caller can set drvdata if desired.
