[ Upstream commit c6721b3c6423d8a348ae885a0f4c85e14f9bf85c ]
Flush queued events when disabling the crtc. This avoids timeouts when
we come back and wait for dependencies (like the previous frame's
flip_done).

[ Upstream commit 95e681ca3b65e4ce3d2537b47672d787b7d30375 ]
_dpu_plane_calc_bw() uses integer variables to calculate the bandwidth
used during plane bandwidth calculations. However for high resolution
displays this overflows easily and leads to below errors
[dpu error]crtc83 failed performance check -7
Promote the intermediate variables to u64 to avoid overflow.
changes in v2:
- change to u64 where actually needed in the math
