video: rockchip: mpp: rkvdec2: Disable irq when soft ccu reset

Browse Source 
1. it is not need save qos when resetting.
2. In the ccu mode, force core idle is an asynchronous operation.
while the core may still be working and will report irq.
However, since it is currently a reset operation, IRQ can directly
disabled without processing.
