Embed video_device structs vdev and vbi_dev in au0828_dev.
With this change, dynamic allocation and error path logic
in au0828_analog_register() is removed as it doesn't need
to allocate and handle allocation errors. Unregister path
doesn't need to free the now static video_device structures,
hence, changed video_device.release in au0828_video_template
to point to video_device_release_empty.

Convert au0828 to use videobuf2. Tested with NTSC.
Tested video and vbi devices with xawtv, tvtime,
and vlc. Ran v4l2-compliance to ensure there are
no failures.
Video compliance test results summary:
Total: 75, Succeeded: 75, Failed: 0, Warnings: 18
Vbi compliance test results summary:
Total: 75, Succeeded: 75, Failed: 0, Warnings: 0

Right now, the au0828 driver uses .tuner to detect if analog
tv is being used or not. By not filling .tuner fields at the
board struct, the I2C core can't do decisions based on it.
So, add a field to explicitly tell when analog TV is supported.
No functional changes.

When DVB is streaming and suspend is called, it will call
au0828_stop_transport(), with will clean the streaming flag.
Due to that, stop_urb_transfer() will be called twice,
causing an oops.
So, we need another flag to be used at resume, telling it
to restart DVB.
While here, add a logic at stop_urb_transfer() to prevent
it of being called twice, and convert the usb_streaming
flag into boolean.

Instead of using printk(KERN_foo, use pr_foo() macros.
No functional changes.
Note: we should do the same for dprintk(), but that would
require to remove the dprintk levels. So, for now, let's
not touch on it.

No timers should be enabled during suspend. So,
stop them. At resume time, we should do the proper
initialization for it to keep working.

The scheduled work should be cancelled during suspend.
At resume time, we need to set the frontend again. So,
add such logic to the driver.

Define au0828_rc_*() stubs to avoid compile errors when
VIDEO_AU0828_RC is disabled and avoid the need to enclose
au0828_rc_*() in ifdef CONFIG_VIDEO_AU0828_RC in .c files.

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.

Added command line parameter preallocate_big_buffers so that the digital
transfer buffers can be allocated when the driver is registered. They
do not have to be allocated every time a feed is started.

Free what was allocated if there is a failure allocating
transfer buffers.
Stop the feed on a start feed error. The stop feed is not always called
if start feed fails. If the feed is not stopped on error, then the driver
will be stuck so that it can never start feeding again.

This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by
creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog
video capture support and depends on VIDEO_V4L2 itself.
With VIDEO_AU0828_V4L2 disabled, the driver will only support digital
television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2
enabled, the driver will be built with the analog v4l2 support included.
By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to
preserve the original behavior.
