[media] cx88: set dev_parent to the correct parent PCI bus
The cx88 driver has one v4l2_device, but the video nodes are owned by two
different PCI busses. So the dev_parent pointer should be set to the correct
parent bus, otherwise sysfs won't show the correct device hierarchy.
This broke starting in 3.6 after a driver change, so this patch resurrects
the correct behavior.

[media] v4l2: always require v4l2_dev, rename parent to dev_parent
The last set of drivers still using the parent field of video_device instead
of the v4l2_dev field have been converted, so v4l2_dev is now always set.
A proper pointer to v4l2_dev is necessary these days otherwise the advanced
debugging ioctls will not work when addressing sub-devices. It also ensures
that the core can always go from a video_device struct to the top-level
v4l2_device struct.
There is still one single use case for the parent pointer: if there are
multiple busses, each being the parent of one or more video nodes, and if
they all share the same v4l2_device struct. In that case one still needs a
parent pointer since the v4l2_device struct can only refer to a single
parent device. The cx88 driver is one such case. Unfortunately, the cx88
failed to set the parent pointer since 3.6. The next patch will correct this.
In order to support this use-case the parent pointer is only renamed to
dev_parent, not removed altogether. It has been renamed to ensure that the
compiler will catch any (possibly out-of-tree) drivers that were missed during
the conversion.

The flush calls at the write side are not necessary anyway since ringbuffer_flush

ringbuffer.

Properly handle tristate dependencies on USB/PCI menus
As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't
simply make the bool menu to be dependent on it. Everything below
the menu should also depend on it, otherwise, we risk to allow
building them with 'y', while only 'm' would be supported.
So, add an IF just before everything below, in order to avoid
such risks.
