As warned by sparse:
	atomisp: drivers/staging/media/atomisp/pci/atomisp_acc.c:508 atomisp_acc_load_extensions() warn: iterator used outside loop: 'acc_fw'

The acc_fw interactor is used outside the loop, at the error handling
logic. On most cases, this is actually safe there, but, if
atomisp_css_set_acc_parameters() has an error, an attempt to use it
will pick an invalid value for acc_fw.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

In order to follow the changes made by the previous patch,
which moved platform/ti-vpe to platform/ti, move the Kconfig
entries to the same place.
Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

The ti-vpe/ sub-directory does not only contain the VPE-specific things.
It also contains the CAL driver, which is a completely different
subsystem. This is also not a good place to add new drivers for other TI
platforms since they will all get mixed up.

Separate the VPE and CAL parts into different sub-directories and rename
the ti-vpe/ sub-directory to ti/. This is now the place where new TI
platform drivers can be added.

Just like media bus drivers, place platform drivers on a
submenu, in order to better organize user-selection:

    Media drivers  --->
	    *** media drivers ***
	[*] Media USB Adapters  --->
	[*] Media PCI Adapters  --->
	-*- Radio Adapters  --->
	[*] Media platform devices  --->
	    *** MMC/SDIO DVB adapters ***
	< > Siano SMS1xxx based MDTV via SDIO interface
	[*] V4L test drivers  --->
	[*] DVB test drivers  --->
	    *** FireWire (IEEE 1394) Adapters ***
	<*> FireDTV and FloppyDTV
	    *** common driver options ***
	[ ] Enable Remote Controller support for Siano devices
	[ ] Enable debugfs for smsdvb

As this submenu depends on MEDIA_PLATFORM_DRIVERS and defaults to "y",
there's no need to change already-existing .config entries, nor touch
the several make *_defconfig.
