The ADV748x handles interlaced media using V4L2_FIELD_ALTERNATE field
types. The correct specification for the height on the mbus is the
image height, in this instance, the field height.
The AFE component already correctly adjusts the height on the mbus, but
the HDMI component got left behind.
Adjust the mbus height to correctly describe the image height of the
fields when processing interlaced video for HDMI pipelines.

The ov9650 driver currently only supports legacy platform data probe.
This change adds device tree probing.
There has been an attempt to add device tree support for ov9650 driver
by Hugues Fruchet as a part of the patchset that adds support of OV9655
camera (http://www.spinics.net/lists/linux-media/msg117903.html), but
it wasn't merged into mainline because creating a separate driver for
OV9655 is preferred.
This is very similar to Hugues's patch, but not supporting new device.
