accel/amdxdna: Switch to always use chained command
Preempt commands are only supported when submitted as chained commands.
To ensure preempt support works consistently, always submit commands in
chained command format.
Set force_cmdlist to true so that single commands are filled using the
chained command layout, enabling correct handling of preempt commands.
