If we pass TDA18271_GATE_DIGITAL into tda18271_attach(), it will always try to
use the digital demodulator's i2c gate.
If we pass TDA18271_GATE_ANALOG into tda18271_attach(), it will always try to

If we pass TDA18271_GATE_AUTO into tda18271_attach(), it will try to use the
analog demodulator's i2c gate when tuning in analog mode, and it will try to
use the digital demodulator's i2c gate when tuning in digital mode.

saa7134 were converted to video_ioctl2, but saa7134_empress weren't. This broke
saa7134-empress, since it were dependent of saa7134_common_ioctl.
With the conversion, the module had a size decrease of 436 bytes on x86_64:

VBI were broken, since there weren't any function handlers for it. This patch
fixes it, by removing the vbi_template, using, instead video_template.
This also saves some space at the data segment.

The pvrusb2 driver tries to keep all device specific attributes in a
single data structure in one source file. This change further cleans
up how that table is set up. We now try to group everything together
for each specific device, and the number of symbols exported from this
module has now been reduced to a single global.

mv_count is a counter used to move the vertical bars. Before this patch, it
where a static var. This works fine for just one device. However, when using
multiple devices, every device would increment it.
This patch moves it to its correct place: struct vivi_dev. So, now, each device
has its own data.

There were a trouble at vivi driver when using non-zero inodes. This where due
to not properly preserving the minor inode after calling video_register. Since
this driver is a reference for newer drivers, and it is possible to have more
than one video device inside the machine, this patch makes vivi to dynamically
allocate video_device struct.
Thanks to Gregor Jasny <jasny@vidsoft.de> for pointing the issue.
Also, this patch removes a very anoying (but useless) message of not having a
proper release call.
