drm/rockchip: vop2: Only wait for changed layer cfg done when there is pending cfgdone bits
The write of cfgdone bits always done at .atomic_flush.
When userspace makes plane zpos changes of two crtc within one commit,
at the .atomic_begin stage, crtcN will never receive the "layer change
cfg done" event of crtcM because crtcM has not yet written "cfgdone".
So only wait when there is pending cfgdone bits to avoid long timeout.
