There are lots of drivers that only work when the media controller
and/or the V4L2 subdev APIs are present.
Right now, someone need to first enable those APIs before
using those drivers.
Well, ideally, drivers, should, instead *optionally*
depend on it, in order for PC camera drivers to be able to use
them, but nowadays most drivers are UVC cameras, with don't
require a sensor driver.
So, be it.
Let's instead make them select the MEDIA_CONTROLLER and the
SUBDEV API, in order to make easier for people to be able
of enabling them.

Support for Exynos4212 SoCs has been removed by commit bca9085e0a

The help text should be indented by at least two spaces after the
'help' separator. This is both good practice and the media_build system
for building media drivers makes this assumption.
I went through all Kconfigs under drivers/media and fixed any bad help
sections. This makes it conform to the common practice and should fix
problems with 'make menuconfig' when using media_build. This is due to
a "WARNING" message that media_build can insert in the Kconfig and that
assumes the help text is indented by at least two spaces. If not, then the
Kconfig becomes invalid and 'make menuconfig' fails.

With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the
individual drivers as built-in code when that should not be possible:
drivers/built-in.o: In function `s5pcsis_set_fmt':
policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image'
drivers/built-in.o: In function `s5pcsis_probe':
policy.c:(.text+0x13b440): undefined reference to `v4l2_of_parse_endpoint'
policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init'
Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency
from CONFIG_V4L2 propates to the individual Kconfig symbols and they
can only be built as loadable modules if V4L2 or any other of the
dependencies itself is a module.

Currently the whole driver depends on MFD_SYSCON, which in turn
depends on OF. To allow to use the driver on non-dt platforms
(S5PV210) the SYSREG support is made conditional (it is needed
only for dt enabled platforms) and MFD_SYSCON is selected if
OF is enabled, instead of depending on OF.

The s5p-fimc directory now contains drivers for multiple IP blocks
found in multiple Samsung application processors. This includes FIMC
(CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver
is going to be put into same directory. Hence we rename it to
exynos4-is as s5p-fimc was only relevant for early version of this
driver, when it only supported FIMC IP block.
The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will
be included in drivers/media/platform/exynos4-is directory, with some
modules shared with exynos5 series, while the rest of exynos5 specific
modules will find their home in drivers/media/platform/exynos5-is.
