saa7134-dvb: add missing dvb_attach around tda10046_attach

This patch adds a possibly missing dvb_attach for tda10046_attach.
This removes the hard dependency of saa7134-dvb on tda1004x module.

I updated the radio-si470x driver another time. Here are the commented history entries:

- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.

- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.

- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.

- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.

This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.

After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.

This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.

Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
  <dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
  struct path in every place where the stack can be traversed
- it reduces the overall code size:

without patch series:
   text    data     bss     dec     hex filename
5321639  858418  715768 6895825  6938d1 vmlinux

5320026  858418  715768 6894212  693284 vmlinux

This patch:

Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
