[GIT PULL] drm/vc4: changes for drm-next.

[Eric Anholt]

These changes have been on the list for just under 2 weeks
(and sitting under a lot of the other development I've been doing), so
I think they're ready to go for -next.  They're also a big deal for
getting multiple encoders going, which I'm hoping will happen soon.

The following changes since commit 5443ce86fa37e7d3cc63d2067d05e3388fdeec17:
