class_device_create_file is marked as __must_check, so its
return value must be checked.

If an error occurs during class_device_register, print an error message,
kfree(class_dev) and return.

Added necessary header file in order for kconfig build options to be
considered at compile time. Without this patch all options will always
be disabled, regardless of whether they are selected or not.

Rework controls internal architecture. Rework video standard
handling. This is a major change.

Arrange things in pvrusb2 so that the sysfs-using component doesn't
have to be compiled in. Control this with new
CONFIG_VIDEO_PVRUSB2_SYSFS variable. This will allow the driver to
still be used even if sysfs has not been compiled into the kernel.
Also arrange things similarly in pvrusb2 for the debug interface,
which is something that normally should not need to be built but is
valuable for bug chasing. This is controlled now with
CONFIG_VIDEO_PVRUSB2_DEBUGIFC.

This problem was introduced by the previous change. It appears that
if you try to create to sysfs entries of the same name in one
directory, then sysfs gets very angry and causes a kernel oops when
you later try to tear down those nodes. By not allocating enough
space to hold the name, we were inadvertently causing a sysfs control
file name collision...

Rework entire internal controls interface to eliminate the need for
visibly defined control IDs which must otherwise be translated by the
V4L2 public interface. As part of this work, internal structures
which mimiced various V4L2 structures (video standards, audio modes)
have been reworked to actually use the native structures. This
triggered a _significant_ rework for how video standards are dealt
with (and what is in place now should be much more flexible and
forgiving for various handling less-common video standards).

Eliminate the need to track the number pvrusb2 CIDs at compile time
from within the pvrusb2 driver. This is part of a control structure
cleanup.
