Russ Weight e9a9970bf5 fpga: dfl: Avoid reads to AFU CSRs during enumeration ... CSR address space for Accelerator Functional Units (AFU) is not available during the early Device Feature List (DFL) enumeration. Early access to this space results in invalid data and port errors. This change adds a condition to prevent an early read from the AFU CSR space.
