Bug description:
[SRU Justification]
Microsoft Azure clouds support the use of a Xilinx FPGA to accelerate
machine learning and other high performance tasks. The master kernels
have had this option since the beginning. The lack of this option for
Azure appears to have been an oversight.
[Fix]
Enable CONFIG_FPGA=m and CONFIG_FPGA_MGR_XILINX_SPI=m. Add these modules to
the inclusion list.
[Test Plan]
modprobe xilinx-spi
[Where problems could occur]
The chances for regression are minimal as all additions are modules.
