[media] exynos4-is: Remove support for non-dt platforms

Browse Source 
All platforms supported by this driver are going to get device tree
support in this kernel release so remove code that would have been
actually not used any more.

6. Platform support
===================
The machine code (arch/arm/plat-samsung and arch/arm/mach-*) must select
following options:
CONFIG_S5P_DEV_FIMC0 mandatory
CONFIG_S5P_DEV_FIMC1 \
CONFIG_S5P_DEV_FIMC2 | optional
CONFIG_S5P_DEV_FIMC3 |
CONFIG_S5P_SETUP_FIMC /
CONFIG_S5P_DEV_CSIS0 \ optional for MIPI-CSI interface
CONFIG_S5P_DEV_CSIS1 /
Except that, relevant s5p_device_fimc? should be registered in the machine code
in addition to a "s5p-fimc-md" platform device to which the media device driver
is bound. The "s5p-fimc-md" device instance is required even if only mem-to-mem
operation is used.
The description of sensor(s) attached to FIMC/MIPI-CSIS camera inputs should be
passed as the "s5p-fimc-md" device platform_data. The platform data structure
is defined in file include/media/s5p_fimc.h.
7. Build
========
This driver depends on following config options:
PLAT_S5P,
PM_RUNTIME,
I2C,
REGULATOR,
VIDEO_V4L2_SUBDEV_API,
If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
optional s5p-csis.ko (MIPI-CSI receiver subdev).
