Fix improper use of dct_active_percent field in DCT interrupt handler
causing DCT to never get enabled. Set dct_active_percent internally before
IPC to ensure correct driver value even if IPC fails.
Set default DCT value to 30 accordingly to HW architecture specification.
Fixes: a19bffb10c ("accel/ivpu: Implement DCT handling")
