The simple-bridge driver supports multiple simple or dumb bridges, covered by different compatible strings but otherwise identical DT bindings. Some of those bridges have undocumented bindings, while others are documented in text form in separate files. Group them all in a single binding and convert it to YAML. The psave-gpios property of the adi,adv7123 is dropped, as it isn't supported by the driver and isn't specified in any DT file upstream. Support for power saving is available through the enable-gpios property that should cover all the needs of the ADV7123 (as the device only has a /PSAVE pin and no enable pin).
