colibri_t20/30: v4l2: max9526 integration

Integrate MAX9526 video decoder support as found on our analogous
camera module (ACM) connected to a Colibri Evaluation carrier board.

The following kernel configuration options are required to be enabled:

CONFIG_VIDEO_V4L2=y
CONFIG_SOC_CAMERA=y
CONFIG_SOC_CAMERA_MAX9526=y
CONFIG_VIDEO_TEGRA=y
