s_std didn't belong in the tuner ops. Stricly speaking it should be part of
the video ops, but it is used by audio and tuner devices as well, so it is
more efficient to make it part of the core ops.

Add missing URB_NO_TRANSFER_DMA_MAP flag, since the use of consistent memory
is not permitted for DMA on the ARM platform.

LinuxStamp).

As reported by Kyle McMartin and Randy Dunlap:

drivers/media/video/au0828/au0828-video.c:1438: error: 'const struct v4l2_subdev_core_ops' has no member named 'g_register'
drivers/media/video/au0828/au0828-video.c:1453: error: 'const struct v4l2_subdev_core_ops' has no member named 's_register'

This patch properly implements those two API ioctls only when debug is
enabled.

subdev calls.

If the analog initialization failed to create the video device, we never
actually add the entry to the au0828_devlist.  Therefore a panic occurs when
unregistering the analog subsystem.

Make it so we only remove the entry from the list if we added it to the list
in the first place.

Move the setup of the analog isoc handler into au0828-video.c, so it does not
occur if there is not an .input section defined for the board.  Also fixes a
case where if there is an input section but the board does not actually have
analog support, the digital support will continue to work as expected.
