The test robot reported: drivers/soc/litex/litex_soc_ctrl.c:143:34: warning: unused variable 'litex_soc_ctrl_of_match' [-Wunused-const-variable] static const struct of_device_id litex_soc_ctrl_of_match[] = { ^ 1 warning generated.
As per the random config device tree is not configured causing the litex_soc_ctrl_of_match match list to not be used. This would usually mean that we cannot even use this driver as it depends on device tree, but as we also have COMPILE_TEST configured we allow it. Fix the warning by surrounding the unused variable with an ifdef CONFIG_OF.
