media: dt-bindings: i2c: toshiba,et8ek8: Convert to DT schema

Convert binding for toshiba,et8ek8 from TXT to YAML format.
Update MAINTAINERS file accordingly. The binding references
video-interface-devices.yaml at top level to inherit flash-leds
property.

-
-Toshiba et8ek8 5MP sensor is an image sensor found in Nokia N900 device
-
-More detailed documentation can be found in
-Documentation/devicetree/bindings/media/video-interfaces.txt .

-
-Mandatory properties
---------------------
-
-- compatible: "toshiba,et8ek8"
-- reg: I2C address (0x3e, or an alternative address)
-- vana-supply: Analogue voltage supply (VANA), 2.8 volts
-- clocks: External clock to the sensor
-- reset-gpios: XSHUTDOWN GPIO. The XSHUTDOWN signal is active low. The sensor
-  is in hardware standby mode when the signal is in the low state.
-
-
-Optional properties
--------------------
-
-- flash-leds: See ../video-interfaces.txt
-- lens-focus: See ../video-interfaces.txt
-
-
-Endpoint node mandatory properties
-----------------------------------
-
-- remote-endpoint: A phandle to the bus receiver's endpoint node.
