Jarod Wilson 35d136c8da [media] ite-cir: 8709 needs to use pnp resource 2
Thanks to the intrepid testing and debugging of Matthijs van Drunen, it
was uncovered that at least some variants of the ITE8709 need to use pnp
resource 2, rather than 0, for things to function properly. Resource 0
has a length of only 1, and if you try to bypass the pnp_port_len check
and use it anyway (with either a length of 1 or 2), the system in
question's trackpad ceased to function.

The circa lirc 0.8.7 lirc_ite8709 driver used resource 2, but the value
was (amusingly) changed to 0 by way of a patch from ITE themselves, so I
don't know if there may be variants where 0 actually *is* correct, but
at least in this case and in the original lirc_ite8709 driver author's
case, it sure looks like 2 is the right value.

This fix should probably be applied to all stable kernels with the
ite-cir driver, lest we nuke more people's trackpads.
