[PATCH v3 2/4] media: platform: visconti: Add Toshiba Visconti Video Input Interface driver

[Yuji Ishikawa]

Add support to Video Input Interface on Toshiba Visconti ARM SoCs.
The interface device includes CSI2 Receiver,
frame grabber and image signal processor.

A driver instance provides three /dev/videoX device files;
one for RGB image capture, another one for optional RGB capture
with different parameters and the last one for RAW capture.

The implementation has two kind of C sources:
* viif_*
  The user interface. It registers a media controller framework instance,
  three V4L2 driver instances and corresponding subdriver instances.
  The driver provides streaming (DMA-BUF) interface
  and vendor specific controls to configure the image signal processor.
  Memory blocks are specified with videobuf2 buffer backed by DMA-BUF.

* hwd_viif_*
  The hardware layer.
  It configures hardware registers following a request from viif_*.c
  This layer communicate with the hardware via registers.
  Memory blocks are specified with 32bit-truncated phisical address.

For media controller framework the driver provides two items;

* ISP subdevice: which controls CSI2 receiver and image signal processor.
* Capture device: which controls video DMAC, videobuf2 buffers.

Currently subdevices support only one default network.

Future plan:
* Power management operations will be added,
  once the visconti clock framework driver supports
  the Video Input Interface hardware.
* When the visconti IOMMU driver (currently under review) is accepted,
  the hardware layer will use 32bit IO virtual address mapped
  by the dedicated IOMMU.

---
Changelog v2:
- Resend v1 because a patch exceeds size limit.

Changelog v3:
- Adapted to media control framework
- Introduced ISP subdevice, capture device
- Remove private IOCTLs and add vendor specific V4L2 controls
- Change function name avoiding camelcase and uppercase letters
