linux-azure: Enable CONFIG_FPGA_MGR_XILINX_SPI for Azure cloud kernel

[Tim Gardner]

[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.
