Extend Intel service layer driver to get the firmware version running at
FPGA device. Therefore FPGA manager driver, one of Intel service layer
driver's client, can decide whether to handle the newly added bitstream
authentication function based on the retrieved firmware version.
Using the version number to detect features is just plain wrong.
You should use something like a bitmap of supported features.
Firmware, which runs at EL3, returns the version to Intel service layer
driver in a 64-bit value at the register. Intel service layer driver
runs at EL1.
