On DFL FPGA devices, the Accelerated Function Unit (AFU), can be
reprogrammed for different functions. It connects to the FPGA
infrastructure("blue bistream") via a Port. Port CSRs are implemented
separately from the AFU CSRs to provide control and status of the Port.
Once valid green bitstream is programmed into the AFU, it allows access
to the AFU CSRs in the AFU MMIO space.
This patch only implements basic driver framework for AFU, including
device file operation framework.
