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.

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.

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

Take note of which sysfs files / groups that the pvrusb2 successfully
creates and only delete those specific items when tearing things

Check __must_check warnings for class_device_register and class_device_create_file

video_device_create_file was declared as a void, but instead should
return the int value of class_device_create_file.

Move the check from bttv-driver.c into v4l2-dev.h, because all other
callers of video_device_create_file must also be checked.

Replace the call to class_device_create_file in videodev.c with
video_device_create_file, as defined in v4l2-dev.h, so that the
return value of class_device_create_file will be checked.

Check the return value of class_device_register in videodev.c and
pvrusb2-sysfs.c

Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner.

The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded
cx23416 hardware MPEG2 encoder.  There are two major variants of this
device; this driver handles both.  Any V4L2 application which
understands MPEG2 video stream data should be able to work with this
device.
