Some webcams handled by both sn9c102 or zc0301 and some gspca subdrivers
(sonixb, sonixj and zc3xx) were not handled when gspca was generated but
not the associated subdrivers.

For the sequence streamon -> streamoff and again s_input, it fails
to lock the signal, since streamoff puts TVP514x into power off state
which leads to failure in sub-sequent s_input.
So add powerup sequence in s_routing (if disabled), since it is
important to lock the signal at this stage.

Contrary to my earlier belief, the ov7670 is not actually an SMBUS device,
though it will pretend to be one if it's in a good mood. Unfortunately,
it's rarely in a good mood, especially on the XO 1.5. So use low-level i2c
I/O instead.

Rework the logic for tracking the amount of data copied to the VBI buffer, to
address problem found where the video lines are several bytes shifted to the
right (and the leading pixels in the first line rendered are garbage). This
would occur because the copy function would advance the pointer when detecting
headers, but the caller would not adjust the length actually copied.

Increase the packets per URB count from 40 to 64. I suspect that whoever was
looking at the usbsnoop captures saw "0x40" packets and mistook it for "40".
As a result of this change, I can see a 25% reduction in the number of
interrupts generated via powertop.
