Subject: [PATCH] include/uapi/linux/xlnx-ai-engine.h: fix
 CONFIG_XILINX_AIE leak

Linux Kconfig options should not be exposed to user space.  This patch fixes
a Linux kernel leak of the CONFIG_XILINX_AIE option by moving the changes
implemented by the CONFIG_XILINX_AIE from the uapi header file to the local
Linux kernel header file.

Upstream: internal AMD jira process
