DFL_FPGA_GET_API_VERSION and DFL_FPGA_CHECK_EXTENSION ioctls are common
ones which need to be supported by all feature devices drivers including
FME and AFU. This patch implements above 2 ioctls in FPGA Accelerated
Function Unit (AFU) driver.

v2: rebased
v3: rebased as driver renamed to fpga-dfl-afu
fix one checkpatch issue
v4: add Acked-by from Alan and Moritz.
v5: rebase, and add DFL_ prefix to APIs.
