The function prototype needed in pvrusb2-v4l2.c has been moved to
v4l2-dev.h. Track that change.

A previous attempt to deal with the upcoming loss of
video_set_drvdata() and video_get_drvdata() resulted in logic which
causes a circular locking dependency - also known as a deadlock. This
changeset attacks the problem in a different manner, using a technique
that no longer requires the problematic mutex (or that private global
array either).

Implement VIDIOC_INT_SET_REGISTER and VIDIOC_INT_GET_REGISTER for the
pvrusb2 driver. This is a debugging aid which will not be enabled
unless CONFIG_VIDEO_ADV_DEBUG has been enabled.

The CONFIG_VIDEO_PVRUSB2_24XXX is not nearly as "experimental" as the
description suggests. So refine the description to better match reality.

Fix broken build when 24XXX support is not selected. This is required
due to the requirement of removing 24XXX ifdef's from the driver
source.

The pvrusb2 driver resolution limits are now programmed the following
way, based on empirical measurements of the hardware:
Vertical max: 480 for NTSC, 576 otherwise
Vertical min: 75 for 24xxx, 17 otherwise
Horizontal max: 720
Horizontal min: 720 for 24xxx, 19 otherwise

Support for 24xxx devices was previously explicitly bracketed with
CONFIG_VIDEO_PVRUSB2_24XXX inside the code because we didn't trust the
stability of these changes. We trust it now; so there's no reason to
leave this out of the driver anymore.

Scaling were not working fine;
Some reserved registers were wrong;
On some situations, saa7115 were not properly being initializated.
Removed some duplicated code.

There are several boards on V4L that can work with several different
helper modules for audio/video encoding/decoding and similar stuff.
This patch adds the capability of choicing between autoselecting the
pertinent helper modules for each driver, or to manually selecting
them.

This change causes the pvrusb2 driver to limit horizontal resolution
to be only 720 if 24xxx device hardware is being used. This is a
workaround for an unsolved problem in the driver where if the
resolution is set to something other than 720 the video quality will
be _seriously_ degraded. It only happens on 24xxx devices (29xxx are
unaffected by the problem and unaffected by this change). Once the
problem is finally solved, this small change can be removed.

The internal control implementation in the pvrusb2 driver normally
encodes integer range limits using literal values in a const
structure. This change adds two function pointers, which if not null
will be called through in order to determine integer min / max
values.

The pvrusb2 implementation for VIDIOC_[S|TRY]_FMT was hardcoding
limits on the range for allowed resolution, but it would be much
better if we instead just queried the internal control for these
values. This then opens the door for the driver to adjust these
limits based on the detected hardware.

Take note of which sysfs files / groups that the pvrusb2 successfully
creates and only delete those specific items when tearing things
down. (Previously we just blindly tore everything down every time.)

Fix a few miscellaneous issues in the pvrusb2 driver related to use of

Previously the pvrusb2 driver was conditionalizing printing of the
device register / unregister messages against a debug mask. This sort
of information should always appear, thus this patch.
