video: rockchip: mpp: No need to save qos when making idle requests

Browse Source 
Playing mpeg2 video will get stuck at the last position.

The reason is that qos will be saved when vdpu2 is reset.
However, the pd-related clock has been turned off, causing
the read and write registers to be stuck.

However, when pd is switched on and off, the qos will be
saved and restored by itself, and for the 3588 platform,
there is no need to save qos before making an idle request.
