EFA devices added support for CRC16 checksum on admin responses and to expose it to the driver the API version increased to 0.2. Add a check for support on device init and if supported validate the checksum on each admin response the driver receives. If the checksum validation failed, drop the CQE. Add the CRC16 module to Kconfig to have the in-tree dependency.
