[PATCHv4 3/7] driver, misc: add Intel Stratix10 service layer driver

From: Richard Gong Some features of the Intel Stratix10 SoC require a level of privilege higher than the kernel is granted. Such secure features include FPGA programming. In terms of the ARMv8 architecture, the kernel runs at Exception Level 1 (EL1), access to the
