Fall back to input 0 if "default-input" property is not present.
Additionally, documentation in commit bf9c82278c34 ("[media]
media: adv7604: ability to read default input port from DT") states
that the "default-input" property should reside directly in the node
for adv7612. Hence, also adjust the parsing to make the implementation
consistent with this.
Based on patch by William Towle <william.towle@xxxxxxxxxxxxxxx>.
