this patch removes unneeded dependency of ARCH_OMAP3
on VIDEO_DM6446_CCDC.
Also the top level platform Makefile descended into
davinci/ without any dependency so just drop the
dependency obj-y, as obj-$(CONFIG_ARCH_DAVINCI)
already exists.

It is possible to call STREAMON without having any buffers queued.
So vb2_is_streaming() can return true without start_streaming()
having been called. Only after at least one buffer has been
queued will start_streaming be called.
The check vb2_is_streaming() is incorrect as this would start
the DMA without having proper DMA pointers set up. this patch
uses vb2_start_streaming_called() instead to check is streaming
was called.

this patch drops setting of vb2 buffer state to VB2_BUF_STATE_ACTIVE,

coda-bit uses kmalloc/kfree functions, so the slab header needs to be included
in order to fix the following build errors:
drivers/media/platform/coda/coda-bit.c: In function 'coda_fill_bitstream':

When vpif is compiled as module, those errors happen:
ERROR: "vpif_lock" [drivers/media/platform/davinci/vpif_display.ko] undefined!
ERROR: "vpif_lock" [drivers/media/platform/davinci/vpif_capture.ko] undefined!
That's because vpif_lock symbol is not exported.

ERROR: "__bad_ndelay" [drivers/media/platform/s5p-jpeg/s5p-jpeg.ko] undefined!
That happens because asm-generic doesn't like any ndelay time
bigger than 20us.
Currently, usleep_range() couldn't simply be used, since
exynos4_jpeg_sw_reset() is called with a spinlock held.
So, let's use udelay() instead.

This driver depends on a legacy OMAP DMA API. So, it won't
compile-test on other archs.
While we might add stubs to the functions, this is not a
good idea, as the hole API should be replaced.
So, for now, let's just remove COMPILE_TEST and wait for
some time for people to fix. If not fixed, then we'll end
by removing this driver as a hole.

instead of testing bools if they are false or true, just use
