drm/i915: implement drmmode overlay support v4
This implements intel overlay support for kms via a device-specific
ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on
dri-devel). We've reached the conclusion that such an infrastructure
only makes sense when multiple kms overlay implementations exists,
which atm don't (and it doesn't look like this is gonna change).
Open issues:
- Runs in sync with the gpu, i.e. unnecessary waiting. I've decided
to wait on this because the hw tends to hang when changing something
in this area. I left some dummy functions as infrastructure.
- polyphase filtering uses a static table.
- uses uninterruptible sleeps. Unfortunately the alternatives may
unnecessarily wedged the hw if/when we timeout too early (and
userspace only overloaded the batch buffers with stuff worth a few
secs of gpu time).
Changes since v1:
- fix off-by-one misconception on my side. This fixes fullscreen
playback.
Changes since v2:
- add underrun detection as spec'ed for i965.
- flush caches properly, fixing visual corruptions.
Changes since v4:
- fix up cache flushing of overlay memory regs.
- killed require_pipe_a logic - it hangs the chip.
