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.

  gpu: ipu-v3: Stop overwriting pdev->dev.of_node of child devices

  drm/imx: imx-tve: Do not set the regulator voltage

Linux 4.10-rc8

Backmerge Linus rc8 to fix some conflicts, but also
to avoid pulling it in via a fixes pull from someone.

Display panels can be oriented many ways, especially in the embedded
world. The rotation property is a way to describe this orientation.
The counter clockwise direction is chosen because that's what fbdev
and drm use.

704a6c008b7942bb7f30bb43d2a6bcad7f543662 broke pci msi rearm for g92 GPUs.

g92 needs the nv46_pci_msi_rearm, where g94+ gpus used nv40_pci_msi_rearm.

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

Tested with piglit's arb_shader_image_load_store-atomicity, which causes
GR to hang in such a way that recovery failed (CTXSW_TIMEOUT continually
re-triggers).

The previous commit simply changes the interface, but should result in
the same behaviour as previously.  This commit has been split out from

FIFO gives us load/save/switch status, and we need to be able to determine
which direction a "switch" is failing during channel recovery.

In order to do this, we apparently need to query the engine itself.

This prevents *very* long waits while attempting to destroy channels

There are instances (such as non-recoverable GPU page faults) where
NVKM decides that a channel's context is no longer viable, and will
be removed from the runlist.

This commit notifies the owner of the channel when this happens, so
it has the opportunity to take some kind of recovery action instead
of hanging.
