[media] au0828: reset streaming when a new frequency is set

As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.

I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.

Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.

There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.

One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.

This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.

A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

[media] v4l: Add source change event

This event indicates that the video device has encountered
a source parameter change during runtime. This can typically be a
resolution change detected by a video decoder OR a format change
detected by an input connector.

This needs to be nofified to the userspace and the application may

[media] ARM: S5PV210: Remove camera support from mach-goni.c

S5PV210 is going to get DT support, so we can remove the camera
bits from the only board using camera on S5PV210. This allows to
clean the exynos4-is driver by dropping code for non-dt platforms.
This patch can be dropped if a patch removing the whole board
file is applied first.

[media] exynos4-is: Free FIMC-IS CPU memory only when allocated

Ensure dma_free_coherent() is not called with incorrect arguments
and only when the memory was actually allocated. This will prevent
possible crashes on error paths of the top level media device driver,
when fimc-is device gets unregistered and its driver detached.

[media] exynos4-is: Fix compilation for !CONFIG_COMMON_CLK

CONFIG_COMMON_CLK is not enabled on S5PV210 platform, so include
some clk API data structures conditionally to avoid compilation
errors. These #ifdefs will be removed for next kernel release,
when the S5PV210 platform moves to DT and the common clk API.
