Add the vpfe capture driver which implements media controller
interface. The driver suports all the setup functionality for
all all units nnamely- ccdc, previewer, resizer, h3a, aew.
The driver supports both dm365 and Dm355.
The driver does isr registration, v4l2 device registration,
media registration and platform driver registrations.
It calls the appropriate subdevs from here to cerate the
appropriate subdevices and media entities.

+ * Driver name : VPFE Capture driver
+ * VPFE Capture driver allows applications to capture and stream video
+ * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ * TVP5146 or Raw Bayer RGB image data from an image sensor
+ * such as Microns' MT9T001, MT9T031 etc.
+ *
+ * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ * consists of a Video Processing Front End (VPFE) for capturing
+ * video/raw image data and Video Processing Back End (VPBE) for displaying
+ * YUV data through an in-built analog encoder or Digital LCD port. This
+ * driver is for capture through VPFE. A typical EVM using these SoCs have
+ * following high level configuration.
+ *
+ * decoder(TVP5146/ YUV/
+ * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ * data input | |
+ * V |
+ * SDRAM |
+ * V
+ * Image Processor
+ * |
+ * V
+ * SDRAM
+ * The data flow happens from a decoder connected to the VPFE over a
+ * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ * and to the input of VPFE through an optional MUX (if more inputs are
+ * to be interfaced on the EVM). The input data is first passed through
+ * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ * does very little or no processing on YUV data and does pre-process Raw
+ * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ * Color Space Conversion (CSC), data gain/offset etc. After this, data
+ * can be written to SDRAM or can be connected to the image processing
+ * block such as IPIPE (on DM355/DM365 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - USERPTR IO
+ * - Capture using TVP5146 over BT.656
+ * - Support for interfacing decoders using sub device model
+ * - Work with DM365 or DM355 or DM6446 CCDC to do Raw Bayer
+ * RGB/YUV data capture to SDRAM.
+ * - Chaining of Image Processor
+ * - SINGLE-SHOT mode
