RISC-V SoC drivers for v6.8

There's only one set of changes here, the addition of "Auto Update"
support for PolarFire SoC. Auto Update is one of the ways that the FPGA
bitstream can be updated, and the only one suitable for use from Linux
as it does not immediately initiate a reboot when started.
The driver was not accepted in the FPGA manager subsystem as the update
only occurs after a reboot and makes no use of the FPGA manager
framework.
