[PATCH v3 3/9] misc: xilinx-ai-engine: Implement AI engine cleanup sequence

when the partition is released, user can set the control flag to indicate not to reset the partition when the user requests the partition. If partition the not to reset partition control flag is set, it will not execute the above cleanup sequence when the partition is released. Signed-off-by:
