media: tegra-video: Add custom V4L2 control V4L2_CID_TEGRA_SYNCPT_TIMEOUT_RETRY

Browse source

This patch adds custom V4L2 control for syncpt timeout retry to continue
capture on error for specified retries count through this control.

This is useful for HDMI-to-CSI bridge debug purposes like for hotplug scenarios
or for ignoring captures till HDMI input is stabilized.
