media: staging: drop omap4iss

The omap4 camera driver has seen no progress since forever, and
now OMAP4 support has also been dropped from u-boot (1). So it is
time to retire this driver.

OMAP4 ISS Driver
================
Author: Sergio Aguirre <sergio.a.aguirre@gmail.com>
Copyright (C) 2012, Texas Instruments
Introduction
------------
The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
Which contains several components that can be categorized in 3 big groups:
- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
- ISP (Image Signal Processor)
- SIMCOP (Still Image Coprocessor)
For more information, please look in [#f1]_ for latest version of:
"OMAP4430 Multimedia Device Silicon Revision 2.x"
As of Revision AB, the ISS is described in detail in section 8.
This driver is supporting **only** the CSI2-A/B interfaces for now.
It makes use of the Media Controller framework [#f2]_, and inherited most of the
code from OMAP3 ISP driver (found under drivers/media/platform/ti/omap3isp/\*),
except that it doesn't need an IOMMU now for ISS buffers memory mapping.
Supports usage of MMAP buffers only (for now).
Tested platforms
----------------
- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
which only the last one is supported, outputting YUV422 frames).
- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
which only the OV5650 are supported, outputting RAW10 frames).
- PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with
following sensors:
* OV5640
* OV5650
- Tested on mainline kernel:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=summary
Tag: v3.3 (commit c16fa4f2ad19908a47c63d8fa436a1178438c7e7)
