imx-drm: TVE regulator, fb size limit, and ipu-v3 module fixes

- Fix i.MX5 TV encoder probing in case no dac-supply regulator
  is set in the device tree.
- Remove 64 pixel min_width/height limit, which unnecessarily
  prohibits creation of small frame buffers.
- Add missing ipu_csi_set_downsize export, for media drivers
  built as modules.
- Stop modifying pdev->dev.of_node for IPU client devices that
  do not have an OF modalias to fix module autoloading.

When the fast blit path fails while attempting to move a buffer from RAM
to VRAM, we fall back to a CPU-based memcpy that cannot handle split VRAM
buffers. Instead of crashing, simply fail the buffer move.

Ideally, we would teach TTM about split buffers so that the fallback still
works in this case, but that is quite involved. So for now, apply the
simplest possible fix.

The vm fault handler relies on the fact that the VMA owns a reference
to the BO. However, once mmap_sem is released, other tasks are free to
destroy the VMA, which can lead to the BO being freed. Fix two code
paths where that can happen, both related to vm fault retries.

Found via a lock debugging warning which flagged &bo->wu_mutex as
locked while being destroyed.

Greatly improves the chances of recovering the GPU from a CTXSW_TIMEOUT.
