[media] v4l: Add Renesas R-Car FDP1 Driver

The FDP1 driver performs advanced de-interlacing on a memory 2 memory
based video stream, and supports conversion from YCbCr/YUV
to RGB pixel formats

+Renesas R-Car Fine Display Processor (FDP1) Driver
+==================================================
+
+The R-Car FDP1 driver implements driver-specific controls as follows.
+
+``V4L2_CID_DEINTERLACING_MODE (menu)``
+    The video deinterlacing mode (such as Bob, Weave, ...). The R-Car FDP1
+    driver implements the following modes.
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+    :widths:       1 4
+
+    * - ``"Progressive" (0)``
+      - The input image video stream is progressive (not interlaced). No
+        deinterlacing is performed. Apart from (optional) format and encoding
+        conversion output frames are identical to the input frames.
+    * - ``"Adaptive 2D/3D" (1)``
+      - Motion adaptive version of 2D and 3D deinterlacing. Use 3D deinterlacing
+        in the presence of fast motion and 2D deinterlacing with diagonal
+        interpolation otherwise.
+    * - ``"Fixed 2D" (2)``
+      - The current field is scaled vertically by averaging adjacent lines to
+        recover missing lines. This method is also known as blending or Line
+        Averaging (LAV).
+    * - ``"Fixed 3D" (3)``
+      - The previous and next fields are averaged to recover lines missing from
+        the current field. This method is also known as Field Averaging (FAV).
+    * - ``"Previous field" (4)``
+      - The current field is weaved with the previous field, i.e. the previous
+        field is used to fill missing lines from the current field. This method
+        is also known as weave deinterlacing.
+    * - ``"Next field" (5)``
+      - The current field is weaved with the next field, i.e. the next field is
+        used to fill missing lines from the current field. This method is also
+        known as weave deinterlacing.
